Frostheart

Way out in the furthest part of the known world a tiny stronghold exists all on its own cut off from the rest of human-kin by monsters that lurk beneath the snow sea. There a little boy called Ash waits for the return of his parents singing a forbidden lullaby to remind him of them... And doing his best to avoid his very very grumpy Yeti guardian Tobu. But life is about to get a whole lot more crazy-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...?.
