I am a late comer to the fantasy fan club. His Dark Materials by Phillip Pullman captured me and now I look for fantasy in the library, bookstore, friend's houses, everywhere!
What do get you mix a fairy and a human? A "Peculiar." Bartholomew is one, and so is his little sister, Hettie. They live in the slums of a "Steampunk" city, just getting by. No one respects them, in fact, their mother tries to hide the fact they're different. It's to no avail. When something supernatural starts killing "Peculiars, " Bartholomew is marked for death.
The Peculiar by Stefan Bachman will appeal to ANY kid, age 8 and up.
