I'm not entirely sure what I think of this book. I like the way the characters are - the way they live and interact, the way they're indomitably teenagers despite the situation they've been living in since they were very young. I like the jellyfish and the kriks (well, I like the way they're written - they're not at all likable as characters go). But what I don't like is the lack of background - I'd really like to know how this bunch of people got marooned on a giant sentient jellyfish. But they can't remember. And I find that really dissatisfying.

Still, I wanted to know what was going to happen next, and I enjoyed Martha's narrative, so overall it was a good read.
