Book Three of the Elfhome series, the follow-up to exciting Wolf Who Rules and the award-winning fantasy-SF novel that started it all, Tinker.

Elfhome. A world of powerful magic, beautiful elves, man-eating trees, frost-breathing wargs, and god-like dragons. Pittsburgh. A city that has been stranded deep in virgin elfin forest to stave off an invasion by the merciless oni. Its population of sixty thousand humans and a handful of elves are pitted in war that will only end in genocide. Winter is coming. Supplies are running low. All political ties are fraying. Hidden somewhere in Pittsburgh's crumbling neighborhoods, a vanguard of oni are growing in number and attacking from the shadows.
