Life has its ups and downs, doesn't it? And Martha and her friends are really sick of going up, and down, and up, and down. After a traumatic event that no one can talk about or even quite remember, they're stuck on a giant killer jellyfish, tantalisingly close to the shore and safety. They've had enough of it. They've decided that they're either going to escape, or die trying. A YA novel like no other, Jelly is touching, funny and truly unique.
