This is a great book. It is a great series to read after you read Harry Potter, Eragon, etc... There is a lot of action, and awesome magic in it, but the magic takes a bit to learn, and to figure out. It is for mature kids, definitely. I reccomend getting the whole series in one book, that is made up of Sabriel (Book 1), Lirael (Book 2), Abhorsen (Book 3), and it includes an extra book called Nicholas Sayre and the Creature in the Case, and it goes with the story also. Overall, Sabriel is a great book, and I would reccomend it to anyone 11 and up.
