The Wishworks Factory's recent battle against Curseworks has left relations between humans and Jinn very strained, and before long, Ben finds himself embroiled in another war. While evil cousin Penelope and Curseworks lawyer, Rottenjaw, try to recruit the disgruntled Jinn to their own army reserves, Ben and Candlewick try to negotiate peace. Ultimately, two precious magical weapons must be located in order to protect Wishworks. And the key to finding these weapons lies deep below the grounds of the factory, submerged— where else?—inside a wishing well!
