#5 in the popular Jon and Lobo military science fiction series. A nanotech-enhanced soldier-of-fortune joins with his A.I.-equipped intelligence and weapons platform (spaceship-sized!) on a mission to acquire forbidden tech that leads Jon to a confrontation with his own shadowy origins on a deadly planet. A substantial portion of Van Name's profits from the Jon and Lobo saga are dedicated to Falling Whistles, a fund for the rehabilitation of child soldiers. Jon and Lobo are back–and enemies on all sides are out to get them. Haunted by memories of children he could not save, Jon Moore becomes so increasingly self-destructive that even his best friend, the hyper-intelligent Predator-Class Assault Vehicle, Lobo, is worried.
