Elfhome: Elfhome, Book 3

Pittsburgh, PA has been magically transported to a world of elves and magic in order to stave off a monstrous invasion of Earth. Now Tinker, once a downtrodden waif from that city, but now a full-blooded elf ruler, must root out and destroy an evil plot that involves the kidnapping and breeding of elf children.

Tinker uncovers ancient secrets and a web of betrayal as she searches for the lost elflings. Meanwhile, the orc-like oni gangster kidnappers will stop at nothing to win, so neither can she. At five foot nothing, Tinker's greatest weapon has always been her intelligence. Politics, she discovers, is a battle of wits, and Tinker comes heavily armed.
