Stones Unturned by Christopher Golden and Thomas Sniegoski - Paperback

A powerful, demonic force has escaped from the infernal realm -- putting the human world in dire peril. It seeks an ally in Danny Ferrick, the youngest member of the Menagerie -- a changeling who is already tormented by his dark, primal urges, the legacy of his demon father.

Tempted into sampling the horrific but thrilling existence of a full-fledged demon, Danny is on the edge of renouncing all that makes him human. Now time is running out for the other members of Doyle's team as they struggle to save their friend from falling into darkness -- and taking all of humanity with him...

MEET THE MENAGERIE
They're as hodge-podge a mix of other-worldly beings as anyone can imagine. But a sorcerer, a scientist, a sixteen-year-old demon, and the others all have one thing in common: a hunger for justice -- no matter what the cost.

They are beings of myth and legend. They possess powers beyond imagining. They are our only hope.
