Books in the Shadow Forest series

Samuel Blink is the hero of this story, but he doesn't know it yet. Right now, he and his sister Martha are in the back of his parents' car. He has no idea a giant log is about to fall from the sky and change his life forever. He doesn't know that he and Martha will be forced to move to Norway and eat their Aunt Eda's smelly brown cheese.

There's one thing every troll child dreads more than anything - and that's the Betterer, the evil troll in Shadow Forest who loves to punish his fellow trolls for their grubby and stupid habits in lots of horrible ways.
