Grumble the troll wants one thing only. Sleep. Long, peaceful, uninterrupted sleep. But living under a bridge means there is always someone clip-clopping, quack-quacking or squelch-squelching over his head. One by one, Grumble bans every noisy creature he meets … then decides to take himself off to find somewhere quieter. Ah, a nice dark cave. Just as he settles in to go to sleep, he finds it might not be the sanctuary he thought. A playful twist on the classic troll tale, full of humour, surprise and very determined animals.
