Douglas Spitzer wants to be one of the "astronauts" selected for the crucial Mission Politzer. And just like astronauts like Buzz Aldrin and Sally Ride, Douglas is brave, adaptable, and self-sacrificing. He's one of the program's best candidates. But if he qualifies, Douglas won't be traveling through space; he'll be launched into alternate realities on a desperate mission to save Earth from a horrific crisis that has our world on the brink of extinction. Unfortunately, it's a mission where everything will go wrong, where Doug-las's training and very humanity will be put to the test, and where a deep-seeded secret could sabotage everything.
