I heard about these books from several of my friends and they all said it was really good. i happened to find them in the library, so i got books 1 and 2 out and got reading! i read both books that night and i was practically in tears when i found out that they didn't have book 3 (not literally, and just to let you know this was last friday - look at the date). So i went straight on here and got it! But I'm still waiting for book 3 to come so I've only read book one and two.
It's set in the age when knights and things were around but it also has really cool things like magic and sorcerers. Each person who has the Gift (magic) has a different colour magic (completely irrelevant but hey). Alanna and Thom are twins, girl and boy, and when they are eleven Lord Alan, their father sends Alanna to a convent and Thom to a place where he can learn to become a knight. But Alanna doesn't want to go to the convent and Thom would rather learn magic. So they switch places, Alanna pretending to be a boy. You don't hear much about Thom really, it is all about Alanna posing as a boy at the palace. It sounds lame, but seriously, it isn't. :)
It is really well written, but with long chapters. :/ I just couldn't put it down!
