i mostly read books for children, so it's hard to choose. off the top of my head, i'll have to go with eleven by lauren myracle, the steps by rachel cohn, dave at night and ella enchanted by gail carson levine, the thief by megan whalen turner, the prydain chronicles by lloyd alexander, and the vivien leigh series by a couple of writers whose names i have yet to commit to memory.
i can probably come up with several more titles if i were to read through the list of books that i've read (yes, i do keep that kind of lists).
(where the heck is the edit button??)
i just want to mention that while i liked the first book in the his dark materials by philip pullman, i can't say the same for the other two books. which reminds me: pullman wrote the scarecrow and his servant, which i found very cute and amusing. read it!
