Abby in Wonderland

Instead of the usual fairy tale, Abby finds herself in the middle of a book, Alice in Wonderland, with two of her friends, plus bossy Penny (who is definitely not a friend), and in order to get back to reality she must solve a curious riddle, find one of her friends who is missing, and somehow avoid getting her head cut off by the Red Queen--and figure out what she is going to tell the other girls if they ever get out of Wonderland.
