Shiver and Linger by Maggie Stiefvater

Continuing my foray into the realm of teen supernatural romance are Shiver and Linger by Maggie Stiefvater.  Grace and Sam find one another in Shiver.  Grace is a girl who is fascinated by the wolves in the forest behind her house until she realizes that there is one she loves and who loves her back.  Sam remembers Grace from the woods and from his time as a wolf.  During the winter, Sam becomes a wolf and runs the woods with his pack but he is drawn again and again to the woods behind Grace's house.  Sam and Grace's new found love is a race against time, winter and a possible cure for Sam's changes.
In Linger, Sam and Grace fight to stay together but Grace has a dangerous secret of her own.  We'll find out how it all turns out in Forever...coming soon.  I like the series so far, it is something I would have read and loved as a teenager.
