'Ben is stuck in a backwater town, his parents have broken up, and he's facing jail time for some very poor choices.

'Essa is stuck in a backwater world, trapped by a vengeful ex-lover and cut off from the Well, the infinite pit lined with doors to countless realities.

'A lucky accident (not so lucky for Ben) frees Essa and now they're both in the Well, with its invisible lizards, cities hung from cats'-cradles and Library made of sand.

'Essa wants revenge. Ben wants a way home. The awakening of an ancient threat to the Well puts both their plans on hold. On the run, their only allies a clockwork spider and a girl made of iron, they'll have to work together to save all the worlds.'
