On a cold spring night in 1952, a huge meteorite fell to earth and obliterated much of the east coast of the United States, including Washington D.C. The ensuing climate cataclysm will soon render the earth inhospitable for humanity, as the last such meteorite did for the dinosaurs. This looming threat calls for a radically accelerated effort to colonize space, and require ...more

After querying, my library sent me this explanation:

I just got this response from one of our selectors regarding The Calculating Stars:

TOR books no longer sells their front-list to libraries. We must wait at least 4 months after the publication date before their new titles will be released to Overdrive for us to purchase. They have decided that library sales may be negatively impacting their retail sales and are participating in a study that will attempt to determine the impacts of libraries on the book market and sales, especially regarding eBooks.

Needless to say, we are disappointed by this decision. EBooks are a popular format and Science Fiction and Fantasy are popular genres for our patrons. If the patron wishes to give any feedback about this change to TOR and their parent company, Macmillan, they may use this email:

Given that the Overdrive release date for Calculating Stars was not merely pushed back by 4+ months, I'm wondering whether or not it will ever reappear on Overdrive.
The Murderbot Diaries series by Martha Wells is also released by TOR. It has yet to disappear from my library's Overdrive, however the Calculating Stars didn't disappear until the publication date.

3.75ish stars.

Mary Robinette Kowal writes some incredible female characters. And they're not stock "strong female" characters either, they're real. In this case Elma is brilliant and capable, but doesn't go on a tirade overthrowing the '50s sexist patriarchy because Kowal wisely wanted to represent things as they actually happened, even in this alt-history where she really could have done whatever she wanted.

It's impressively well researched and feels just as real as the actual space race. The

I'll go out on a limb here and be mightily surprised if this novel doesn't get nommed for Hugo out of this year's candidates. It has all the right qualities, from good writing, exciting story, delicious premise, and timely application of hot topics and social issues.

Huh? Well, it's like an alternate reality where a meteorite wipes out DC in the 1950's and forces everyone to get into gear with the space program for the best of all reasons... SURVIVAL OF THE HUMAN SPECIES.

Opposable Thumbs: “The Calculating Stars” by Mary Robinette Kowal

“There is nothing to see but that vast blackness. Intellectually, I know that we’ve passed into the dark side of the Earth. We slide into her shadow and then magic fills the sky. The stars come out. Millions of them in crisp, vivid splendor. These are not the stars that I remember from before the Meteor. These are clear and steady, without an atmosphere to make them twink

I've read the short story of this series some time ago and was speechless by how wonderful it was. Naturally, I had to give the novel a chance. And I certainly didn't regret it!

In March 1952, a meteorite strikes Earth. It lands in a body of water which, as it turns out, is even worse than if it had hit land. The protagonist, Elma, is on vacation with her husband (they are newly weds) in some mountains. He's an engineer and responsible for a US satellite program while she is a former WASP pilot (

Yep. All five. What a wonderful ride this book was. I'll say more later.


A good, solid alternate history; a very involving story; characters I can believe in, invest in, and even identify with; and an author whose capabilities, established in earlier books, make the catharsis of reading this book as bracing as a pitcher of 'tinis.

The Lady Astronaut of Mars, book 2.5 in the series that (chronologically) begins with this book, won the 2014 Hugo for Best Novelette. There is a reason this

I realise that my somewhat insipid 3 star rating is at odds with the majority of glowing reviews here.

I see what she was trying to do, I really do, but I can't shake the feeling that MRK has tried to squeeze too many issues into one book.

Let’s count. Main PoV character, Elma, is discriminated against because she is a woman. Also, people don't understand her Jewish heritage. She has mental health problems. Many of her friends experience racial discrimination. The public at large don't believe the

An empowering story for women, The Calculating Stars has a diverse cast of characters and plot that feel real enough to be a biography. This would be great for fans of “Hidden Figures” or to inspire young girls into STEM. The extent of aerospace and historical details were impressive to the point where I assumed the author must have had some experience as an astronaut before. I was also impressed by Kowal exploring discrimination across race, gender, and mental health within the aerospace indust ...more

Definitely one of my favourite books of 2018.

And to think I considered giving this a miss. I'm interested in space, but an alternate history of space exploration? What a colossal mistake giving this a pass would have been.

This is a masterful alt history set in the 1950's that illuminates the very real issues of discrimination. Elma's character suffers painfully from discrimination because she is a woman. On top of that she is fighting a personal battle with severe anxiety. At the same time, whil

I haven't been this disappointed by a book in a long time. I should learn not to get my hopes up so high, but this one really pulled the wool over my eyes. It is a continuation of a story I did like: I read the short story (called "novelette") of Kowal's featuring the main character, Elma York. It's a simple but well-written story, and I considered Elma to have both heart and gumption. I liked her a lot. The story won a Hugo award, which is pretty notable.

A beautifully researched and told alternate version of the space race from the point of view of brilliant woman pilot, scientist and mathematician with dreams of going to space.

It's 1952, and Elma and Nathaniel Wexler are vacationing in the mountains when a massive meteorite strikes just off the US coast in Chesepeake Bay. Much of the East Coast, including Washington DC is destroyed or flooded, and it's only Elma's and Nathaniel's quick thinking in the face of the disaster that save them both. E

I really felt like listening to a sci-fi book and this one was in my audible recommended list. So without thinking too much about it, I started listening. What I got was not entirely what I expected. It's not so much a sci-fi as it is a historical fiction, alternate reality book. A REALLY good one!

It's the USA in the 1950's. The Second World War may be over, but humanity is dealt another blow when a meteorite lands on Washington and obliterates the entire government and hundreds of thousands of

This book was okay. Nothing amazing though. Here's why:

I've read something like this, and it was better. It was different, but the overall premise is the same. I point you toward Neal Stephenson's Seveneves. His book is so much better than this one. Yes, I agree that they are different in a lot of ways, but fundamentally, they are about saving the human race as the planet dies, with women being the key to the success.

Mary's book empowers women, and I get that that is a primary focus...but I fe

I'm always excited to read astronaut books, as you might know from my posts like this one, this one or this one. So I was even more excited to read one where women fight their ground to get to be astronauts. As it turned out, it was not an easy fight, even if it's one written in an alternate 50's Earth. The Calculating Stars is no bright and easy read, but it deals with some really important topics, and is also very engaging and strong.

This is a stirring and surprisingly intimate exploration of an inspired “what-if?” scenario: what if a globally-scaled natural disaster accelerated our space program? The resulting story feels extremely authentic and altogether possible, grounded by the entirely relatable narrator, a genius but altogether human Lady Astronaut. It’s incredibly refreshing to encounter a character whose intelligence and courage don’t always protect her from her own anxieties, nor from the machinations of a fearful, ...more

After reading about Elma as an old woman in Kowal's "The Lady Astronaut", I knew I had to read this story of an alternative history of space flight. After a literal, huge bang at the start, the book takes us on a character journey, as a young Elma, already an accomplished pilot, becomes a Computer, along with many other women, as part of an international effort to get to space. As this is the 1950s, sexism, racism and Jim Crow are alive and well, with many, very capable non-white women passed ov ...more

Super cool premise! But it felt like she was trying so hard to do justice to the women who inspired the story, that actually it got in the way of it feeling realistic.
Since I‘ve read and loved Mary Robinette Kowal’s 2014 Hugo winning novelette The Lady Astronaut of Mars (which now has been moved to book 4.5 in this series – as Goodreads is telling me) I really expected to love this book. But it wasn’t to be.

It all starts in 1952 with a meteorite striking Earth and accelerating the greenhouse effect to the point where the planet might not be inhabitable in the near future and humans have to look beyond Earth and increase their efforts to reach for the stars a

This is one of those books that is objectively good - interesting premise, well-defined characters, sturdy prose and story structure, sufficiently exciting climax, etc. Its un-shy about its feminist/progressive perspective, which I should be fine with because I'm a big 'ol pinko lefty myself, but there's a big difference between positioning your ideology within a narrative and pandering to a particular kind of reader. The Calculating Stars does the latter. Like it desperately needed me to congra ...more

This novel was utterly fantastic. I cursed every hour of work that kept me away from it!

The plot of the novel -- a devastating meteor strike means that Earth must accelerate the space program -- is fascinating enough. Then you throw in the diversity and the civil rights issues and the awful sexism that needs to go away for it all to be successful and that makes the book even better. But what makes this absolutely stunning is the voice. Elma is just an absolute joy to read.

I just loved this. A very very real alternate history of the space program, starting in a disaster that lends it much more of an urgency than a Cold War race to the stars. Features a wonderful main character!
Earlier this year, I read "The Lady Astronaut of Mars" by Mary Robinette Kowal ( and fell in love with Elma York really hard. That tiny little story packed such a huge punch about love, grief, passion and space: it took me a few days to recover... and it was less than 50 pages! When I heard there would be two upcoming Lady Astronaut novels, I actually screamed. And dropped everything else I was reading almost as soon as my copy was delivered.

This book covers a lot: feminism, mental health, civil rights, and climate change, just to name a few things.
I'm a sucker for alternative history, and this starts out as that: a meteorite takes out Washington, D.C. in 1952. The space race is on, but with a twist---the lady "computers" get a much bigger role.
Engaging read, fast-paced, with real *jargon* written by actual astronauts.
Great for fans of Stephenson's "Seven Eves," "Hidden Figures," any alternate history, or Ben Bova's hard SF.

At first glance a story about the apocalypse—a meteor strikes Earth in the 1950s with devastating longterm effects. At second glance this is more an exploration of discrimination against women and persons of colour in that time in the US. And an exploration of the Space Race, this time not against the Russians, but against the end of the world.

I really enjoyed this. I'm a sucker for books involving space, and I loved the enthusiastic geekery that runs throughout the entire book. What a gem.
Utterly compelling read that uses an alternative history of earth following an extinction level event to compel the space programme to hasten humanity's attempts to reach for the stars.

After a meteorite hits off the east coast of the USA in 1952 it causes a cataclysmic change to the global climate. The book follows the story of pilot and mathematician Elma York as she fights bureaucracy and sexism to become a so-called Lady Astronaut in humanity's attempts to colonise outer space. The book also

This book is full of science and feels. It's intense from the start, with a meteorite impact right off the eastern coast of the United States. Elma and her husband survive thanks to their science know-how--she's a WWII WASP and a computer for the rocket program, and he's a lead engineer--but as they assist the rebirth of the government, they stumble upon the awful truth that this is an extinction-level event. Humankind will need to depart the planet to survive.
