Night Rise - Anthony Horowitz:
This is the 3rd book in "The Power of Five" trilogy. Yes, I am reading my teenagers books, and am loving every page. It is great, easy, reading and Horowitz does keep you reading. Have also enjoyed the Garth Nix series : Sabriel, Lirael, and Abhorssen. (Also teen books). Must admit I love the surreal and the opportunity to escape reality. Try these, you might be surprised. Happy reading
