Inventory

Hidden under a small suburban town, the Inventory is a collection of the most incredible technology the world has NEVER seen: invisible camouflage, HoverBoots, indestructible metals, and the deadly war robot Iron Fist. Dev's uncle, Charlie Parker, is the Inventory's mild-mannered curator, with security provided by Eema, a beyond-state-of-the-art artificial intelligence system. But security is catastrophically breached when Lot and Mason from school turn up unexpectedly and, hot on their heels, a ruthless gang of thieves working for the Collector and the Shadow Helix organization. If the thieves succeed in their goal to seize the Iron Fist, Dev, his friends, and the world are in a whole heap of trouble.
