I have read it, once, from the library and I now have my own copy of it. I liked revisiting the rabbits, but it always felt like a collection of stories to me, rather than a 'proper' novel, sort of like how I feel with Tolkien's Silmarillion. One thing that I would have enjoyed would have been a book about the warren in Nutley Copse, and one that told the story of Campion before Holly and his group went to Efrafa, but I suppose that's what fan fic is for. It is a disappointment in that the book doesn't go as deep as Watership Down, but if you look at it as just a bunch of tales then it's not that bad as I've come across worse.
