Flowers in the Attic, by Virginia Andrews

After you've read it, the plot in some ways might seem unbelievable - but at the time it certainly grips.... which is just what you want from a book when you're in a 'can't-and-don't-want-to-put-it-down-till-I've-finished' kinda mood

good book found it hard to put down

Really good book, keeps you interested all the way through and sends you through lots of emotions.
