Two men desire you. Do you run, or go with the flow? Three years ago, over the course of a summer, best friends and half-blooded shapeshifters Nathan and Lena went from friends to lovers. Now just friends again, they come to realize that their brief fling set the groundwork for the fantasies that haunt them. Nathan’s current lover, Armand, is another half-Therian who has had his fill of poly relationships. But watching Nathan and Lena together, Armand dreams of once more being drenched in love and desire from all sides. Their aching cycle of longing and retreat goes on, unfulfilled—until summer heat brings out the animal in them all.
