Before you face the darkest gang of all, you need to meet the boy who became a horse, transformed back into a human , and the bully who was broken.

✨ Gizmo and Razor Jack vs. the Darkest Gang is the thrilling fourth volume in the Gizmo series, a heart-pounding adventure of friendship, justice, and choosing light over darkness—even when it hurts.

After the events of Book 1: Zoo Boy Gizmo, Book 2: Gizmo's Great Escape, and Book 3: Gizmo Challenges Razor Jack, our heroes have come a long way. But now, a year later, everything is at stake.

A ruthless gang has invaded the city. They steal, destroy, and force kids into dangerous crimes. When Gizmo's sister is kidnapped and Razor Jack's mother is murdered, the boys must make an unthinkable choice: go undercover, pretend to join the gang, and risk losing themselves—or do nothing and let evil win.

But kindness is a strength, not a weakness. And in this unforgettable middle-grade novel packed with action, emotion, and meaning, Gizmo and Razor Jack discover what it truly takes to be heroes.
