Query: Against the odds

Wen Spencer obviously loves a challenge. In Tinker he starts with an adolescent female protagonist who becomes involved with ELVES, for gosh sake, as Pittsburg shuttles back and forth between earth and "Elfhome." Out of this mish-mash he has created a series of characters with enough depth so that I actually cared what happened to them. A deft plot with multiple twists and turns kept surprising me. I found this book to be a page turner. Normally, I read several books at once, but in this case, I read only Tinker until it was gone and then wanted more. If I were to quibble, I would say rent a room in Indianapolis or somewhere--the Pittsburg setting has limits (although that's clearly one of those self-imposed obstacles he overcomes.) If he really wants a challenge, why not start his next book with "It was a dark and stormy night." Overall, this is one of the better new authors, and I thoroughly enjoyed the book.
