Final Orbit

By Chris Hadfield

An edge-of-your-seat thriller about China's secret role in the space race--written by the New York Times bestselling author of The Apollo Murders and one of the most experienced astronauts alive.

Houston, 1975. A new Apollo mission launches into orbit, on course to dock with a Russian Soyuz craft: three NASA astronauts and three cosmonauts, joining to celebrate a new dawn of Soviet-American cooperation. But as NASA Flight Controller Kaz Zemeckis listens in from Earth, a deadly accident onboard the orbiting spacecraft changes everything.

Meanwhile, from a remote location in east Asia, the first Chinese spacecraft secretly launches. On board is China's first astronaut, Fang Kuo-chun, whose mission puts him on a collision course with the Apollo crew.

As Kaz races against an enemy on the ground and for answers beyond the sky, the safety of the remaining crew hangs in the balance...

Perfect for fans of Project Hail Mary and filled with shocking twists and real history--including the fascinating story of Professor Tsien Hsue-shen, the "Father of Chinese Rocketry" and founder of China's space program--Final Orbit accelerates to a thrilling conclusion that captures the beauty and terror of survival 270 miles above Earth, as could only be written by one of the world's most experienced astronauts.

"Another terrific thriller from a writer who is uniquely qualified to write it." --Booklist

"Action-filled, believable drama that flows. Readers of sci-fi thrillers by Isaac Asimov, Andy Weir, and James Michener will enjoy the realism of Hadfield's latest." --Library Journal (starred review)

"Possibly the most realistic depiction of a battle between two spacecraft ever written....Hadfield expertly weaves fact, fiction, and his own experiences in orbit to produce a novel that is both technical and entertaining. A master of the genre." --New Scientist
