the House of Night series

Wow. I've recently been reading the House of Night series of books, by PC Cast. I've read 6 of them and could hardly put them down. They are along the lines of the Twighlight trilogy. A young girl is at her school locker, sees a man, feels ill and discovers that she has been Marked. She now has to get to the House of Night, to be around other vampires, or else she will die. What a rude awakening to find out that she is to become the new High Priestess. Some love her, some hate her and don't forget all of the typical high school drama. Throw in all of the dark business, need for blood, imprinting and the struggle to save humanity and you have a whirlwind series that many would love to read. Some of the content is strong language, a curse here and there, and some sexual references. I'd let my 7th grader read it, because we've talked about such things.
