Frostheart

Way out in the furthest part of the known world, a tiny stronghold exists all on its own. There, a boy called Ash waits for the return of his parents, doing his best to avoid his very grumpy yeti guardian, Tobu. But life is about to get a whole lot more adventurous for Ash. When a brave rescue attempt reveals he has amazing magical powers, he's whisked aboard the Frostheart, a sleigh packed full of daring explorers who could use his help. But can they help him find his family . . . ?
