Booklist: The first half of Kowal’s two-book tale—The Fated Sky will follow—begins in 1952 when a meteorite strikes Earth, causing a global cataclysm.

The eastern coast of the U.S. crumbles, and the rest of the world faces a climate shift. A former WASP pilot and a brilliant mathematician, Elma York works for the International Aerospace Coalition, along with her engineer husband, expediting efforts to colonize other planets. Recognizing that she and her female colleagues are just as qualified as the men, Elma fights for their right to become astronauts. She builds momentum for their cause by hosting a women-only air demonstration, speaking on a Bill Nye–type kids show, and passing tests with ridiculous rules her male counterparts would never be asked to endure.

Although Kowal’s latest is a definite deviation from her popular Glamour Histories series, she once again strikes a fine balance of integrating historical accuracy—including mid-twentieth-century sexism, racism, and technology—with speculative storytelling. Readers will root for Elma as she breaks barriers and calculates lifesaving equations, all while dealing with sometimes-crippling anxiety. Recommend to fans of realistic sf.

Booklist: Drayden’s latest is a dark, riveting tale about two brothers at odds that explores what it truly means to possess virtues, what it truly means to possess vices, and what it truly means to be brothers.

Auben Mutze is a twin. His lesser status as the inferior twin is marked by six brands down his arm, and each brand symbolizes a vice he possesses. In contrast, Auben’s twin brother, Kasim, possesses only one vice. The single vice marks Kasim as the supposedly superior twin. The twins’ different stations in life and Auben’s jealousy morph their brotherly relationship into one steeped in rivalry. Their brotherly bond is threatened to the point of breaking when Auben begins to hear dangerous voices that whisper of evil, heinous deeds, encouraging him to walk a dark path. If Auben doesn’t rid himself of the voices, he could completely lose himself to them.

Drayden (The Prey of Gods, 2017) excels at making every twist and turn of the plot meaningful to the story. Moreover, the world-building is deliciously lush and complex; any possible initial confusion becomes part of the thrill of puzzling this world out.

Locus: So much about how Kowal structures Elma’s journey works, from her early days as a math whiz and the effect it had on her psyche, through her growth as a competent and confident professional. Equally lovely is the supportive and charming relationship between Nathaniel and Elma. You can’t help but root them both on.

The back third of The Calculating Stars is both intellectually and emotionally satisfying – and nicely sets up The Fated Sky, which is the second half of Elma’s story. Just one month after The Calculating Stars’ release, we’ll finally learn exactly how Elma got herself to Mars.
