These books are great! It's about these four Clans of wild cats and how they survive. They're really cool! I've heard that the author, Erin Hunter, is really a pseudonym for three people. The only thing I don't like is that the series keeps going on and on. There are like seventeen books or something!!! And they all repeat the same themes. The first series is the best. I would recommend reading the first series and the first three books in the second series. Everything else gets pretty boring. But I still love it!!!!!
