This, as I'm sure we all know, is an overheated genre. [[Hush, Hush by Becca Fitzpatrick]] is also free from an entirely happy ending in which all loose ends are tied up. [[Angel by Cliff McNish]] is set in the UK - which makes a nice change from the American freshmen, juniors and seniors - and has more in the way of philosophy and less in the way of snogging.
