Not so graphic - naturally. I read it at about 12-13, read it to my boy at about 10. And yes, there's some difficult stuff in there. Just because it's a cartoon about rabbits doesn't make it easy - but hearing it read to you by a trusted adult over a good few nights is a lot easier. You can stop and discuss... And it's brilliant. A rabbit language, mythology/religion/folklore, political systems, enemies, predators, humour, love, care, bravery, sacrifice... Man. But she's six. So not yet.
