Bone Hunt

This is a story about a boy and his dinosaur... Meet Ryan. He's returned to Singapore after years in America and made to go to a school where he has exactly NO friends. Not one. Worse, there's a bully who's out to get him and lessons are incredibly incredibly dull, until... a new teacher arrives. And along with him, he brings a surprise. Little does Ryan realise that he will soon embark on an incredible journey through time to meet a T-Rex, discover ancient cave paintings and be chased by a sabre-tooth tiger!
