Absolutely loved it when I was younger - I just wish I could've found the whole series - pretty hard in a small town. Warrior cat series by Erin Hunter. Leafpool is pictured. Can't wait for the First Battle!

and then I agree with them that reading a book about heart-wrenching betrayal, love that can never be, and cats brutally killing each other is definitely girly and childish, just because the cats live in a fantasy world and can TALK!
