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.
