Once upon another time
(Book)

Lena has a problem: she is a twelve-year-old giant child, but she is still only the size of a human: rejected by the giant king, she and her enormous talking cat, Rufus, go down to the human world seeking some magic that will restore her to her rightful status; Jin is a twelve-year-old genie, not yet allowed his full powers, and at the moment tied, for two more wishes, to the Golden King, an annoying, nasty tyrant who has sent him on a quest--and when these two children meet all the kingdoms may be changed forever.

Ages 8 to 12.,Aladdin
