Space Case

Stuart Gibbs · 2014
84/100
👍 Worth It

Stuart Gibbs pulls off something genuinely difficult here — a tightly plotted locked-room murder mystery that works because the lunar setting is not decoration but integral to every clue and constraint. The New York Times called it a 'delightful and brilliantly constructed middle-grade thriller' and the multiple state award nominations back that up; this is one of the stronger middle-grade sci-fi mysteries in the catalog.
