About This Book
Tool races through the ruined city, heart pounding, senses sharper than any human’s. His pack of soldier boys follows, but enemies are closing in fast. Just as the trap snaps shut, Tool faces a choice that could change everything—will he fight or fall?
Quick Assessment

The story explores themes of identity, obedience, and resistance, with some intense action and moral complexity appropriate for middle-grade readers aged 9-12.
