Four years ago, the werewolf Alpha Cassian's fated mate Elias was burned to death in a fire. Since then, he has endured each annual rut by self-mutilation alone. Until the mysterious flower shop owner Wren appeared—and somehow calmed his frenzy. Wren carries Elias's scent and birthmark. It turns out that Wren is Elias reborn, reshaped by dark magic, with his memories sealed away. The two fall in love amidst the mystery of his identity, while uncovering that the real arsonist was Cassian's younger brother Theo, and the mastermind behind it was the witch Morwen. In the end, Cassian and Wren perform the "Rite of the Twin Moons," fusing their souls and being reborn, establishing the "Twin Moon Pack." But deep in the forest, the Ancient Father has already awakened.
