Atlantis Rising — T.A. Barron

In a magical land called Ellegandia, a young boy named Promi scrapes by, stealing pies, cakes and sweets to survive. But little does he know that his country is a pawn in an ages-old war between good and evil, battled both in the spirit realm and in the human world. Harboring secrets of his own, Promi teams up with a courageous girl named Atlanta and the two vow to save their land -- and each other -- no matter the cost. But their vow has greater repercussions than they ever could imagine -- in fact, it may just bring about the creation of Atlantis, an island cut off from the rest of the world, where magic reigns supreme.
