Some race to win. Others race to survive. It happens at the start of every November: the Scorpio Races. Riders attempt to keep hold of their water horses long enough to make it to the finish line. Some riders live. Others die. At age nineteen, Sean Kendrick is the returning champion. He is a young man of few words, and if he has any fears, he keeps them buried deep, where no one else can see them. Puck Connolly is different. She never meant to ride in the Scorpio Races. But fate hasn’t given her much of a choice. So she enters the competition - the first girl ever to do so. She is in no way prepared for what is going to happen. 

For years, Grace has watched the wolves in the woods behind her house. One yellow-eyed wolf—her wolf—is a chilling presence she can’t seem to live without. Meanwhile, Sam has lived two lives: In winter, the frozen woods, the protection of the pack, and the silent company of a fearless girl. In summer, a few precious months of being human until the cold makes him shift back again. Now, Grace meets a yellow-eyed boy whose familiarity takes her breath away. It’s her wolf. It has to be. But as winter nears, Sam must fight to stay human or risk losing himself, and Grace, forever.
