Shiver by Maggie Stiefvater, The Wolves of Mercy Falls Series

It's winter and 16 year old Grace watches for the yellow-eyed wolf . She's never seen him in the summer. Ten years ago, his pack tore her from her swing and dragged her into the woods. But "her wolf", with the brilliant yellow eyes, saved her. Finally, she spots him, camouflaged by the trees, but she's memorized those eyes. It's her wolf, and each summer, that first glimpse takes her breath away. She's missed him so. 

Then come summer and Grace meets Sam, a boy her age, who has yellow eyes. Can it be? Grace doesn't know how, but she's certain he has to be the wolf she's come to love.

Sam can't believe his luck. He has watched her from the woods, his Grace, for so long. And now, here she is, in his arms. He won't think about winter, when the degrees start to drop, and the cold will eventually turn him back into a wolf. How can he leave his Grace, he's just found her? But summer won't last forever. 

Maggie Stiefvater has woven a wonderful, imaginative love story, full of suspense. 4 Stars.

And best of all, it's a trilogy!
