When Dr. Holtz’s body is discovered just outside the lunar colony, everyone assumes he made a mistake putting on his spacesuit—but 12-year-old Dashiell “Dash” Gibson has reason to believe this was no accident.
Earth’s first space base has been a living hell for Dash. There’s not much to do on the moon besides schoolwork and virtual-reality gaming, and there’s only a handful of kids his age up there with him. The chance to solve a murder is exactly the type of excitement Dash needs. As clues are found and secrets are uncovered, Dash comes to understand that some of the base’s residents aren’t what they seem to be. With a small cast of characters supplying an excellent variety of suspects, Gibbs creates the best kind of “murder on a train” mystery. The genius, however, is putting the train in space. Closed quarters and techno–mumbo-jumbo add delightful color to the proceedings. Thankfully, the author doesn’t let the high-concept setting overshadow the novel’s mystery. The whodunit is smartly paced and intricately plotted. Best of all, the reveal is actually worth all the buildup. Thrillers too often fly off the rails in their final moments, but the author’s steady hand keeps everything here on track.
Fully absorbing. (Mystery. 9-12)
