Battle Of The Wolves!
Nightshade by Andrea Cremer
Shiver by Maggie Stiefvater
Calla Tor has always known her destiny: After graduating from the Mountain School, she'll be the mate of sexy alpha wolf Ren Laroche and fight with him, side by side, ruling their pack and guarding sacred sites for the Keepers. But when she violates her masters' laws by saving a beautiful human boy out for a hike, Calla begins to question her fate, her existence, and the very essence of the world she has known. By following her heart, she might lose everything - including her own life. Is forbidden love worth the ultimate sacrifice?
Grace and Sam share a kinship so close they could be lovers or siblings. But they also share a problem. When the temperature slips towards freezing, Sam reverts to his wolf identity and must retreat into the woods to protect his pack. He worries that eventually his human side will fade away and he will be left howling alone at the lonely moon.
I've only read Nightshade which I extremely enjoyed and haven't heard that many great things about Shiver. But, it's all up to you since I'm not allowed to vote.
