In Book 2 of The Catherine Wheel Series, Dr. Wheel learns of the existence of a massive decades-long mission to a distant planet when NASA declares it needs her expertise. Endangered by an unknown saboteur, the mission is jeopardized when one of its cargo vessels falls out of synch with the rest of the fleet. When Catherine agrees to help find a solution to the crisis, she has no idea of the bombshell from her own past that is about to change everything.
