This is a book that I just read the other day and thought was excellent.
I spotted it in the library on a display shelf and had a quick look and it looked interesting so I thought I'd borrow it.
I read it all in one go, though it's a pretty big book.
I think the cover is beautiful.
I found it really interesting at the beginning because it's about a teenage girl quite like other teenagers I've known, though she wouldn't really be my sort of person, if I knew her I might not be that interested in become a close friend. However, as it goes on you see a bit more depth in the character and as her final day continues to loop, you see her begin to develop and change as a result of what's happening.
It's definitely worth a read :).
