As a non-fiction writer, Michael Cassutt has written some of the most important and notable space flight books ever, books which astronauts and cosmonauts themselves use to learn about the past and present of space exploration. There are, of course, many insider stories that CAN'T be told while the subjects involved are still alive. With this marvellous novel, Cassutt has created a very believable and thrilling premise, full of highly accurate detail on the space programs of three different nations, and created a fascinating, gripping thriller that had me eager to read more throughout. On a different but equally entertaining level, Cassutt has added in a good number of true-but-subtly-fictionalized stories, that let the reader know what really goes on behind the public image of the space agencies. Only someone with detailed insider knowledge, plus a great talent for telling a story could have pulled this off - and luckily Cassutt has both in abundance. A great book that I highly recommend and will greatly enjoy re-reading.
