She can't survive in his world; he can't stay sane in hers
A twenty-first century ice age dulls the magic that emanates from the earth. Shane Sullivan is a lone wolf above the freeze line. He has no desire to join the packs that range closer to the border, where feral instincts can turn a man into a monster. Not until the winter solstice, when he stumbles across a dying witch who needs his help to get back to her peopleand her magicin the south.
Nadia is a powerful woman in her own world, but she's been drained by her escape from captivity in a northern lab. She knows it's foolhardy to trust a werewolf, but he's her only chance to survive the vast white wilderness. The farther south they travel, the harder it is for Shane to keep the beast within under control, and as their mutual attraction intensifies, Nadia's no longer sure she wants him to.
