This isn't a typical fantasy, but fans of quirky, humorous books like The Hitchhiker's Guide to the Galaxy will find Tom a hero they will like.
This was a very fresh and singular book. Young Adult in feel (with all that making out with Lindsy), but with nothing objectionable. Understanding and use of fantasy tropes in unexpected ways makes this really funny, as does all the gross or goofy details, like the rusty donation box as a portal, the Rat Snottery, etc. I liked Tom's insecurity about being with Lindsy, and also his love-hate relationship with Tom. The writing is simple but not wooden or inexpert-- it just reads like a very talented 15-year-old wrote it, which has its charm. This may be the book I buy for a Christmas present for my son.
