"He was my sworn enemy. Now, he is my eternal shackle." As the sole heir to the Bloodmoon Dagger, Selene Ashton lived for one purpose: to slaughter the werewolf who murdered her parents. But on the night of her ultimate revenge, the tables turned in the most humiliating way. Trapped in the dark, she was publicly claimed by her mortal enemy—Caine Bloodspear, the ruthless Alpha of the rival werewolf empire. Marked as his fated mate in front of his entire pack, Selene instantly became the laughingstock of the supernatural underworld and the ultimate prey. He is a tyrant driven by bloodlust and iron, ready to crush any weakness—even if it's the mate carved into his soul. She is a frozen weapon forged to destroy him, now trapped in a cage of forbidden desire. As a fragile cold war shatters into all-out war, Selene must uncover the dark secrets buried by her own flesh and blood—her uncle Viktor, who manipulated her entire tragedy for a throne. When fate binds the assassin to her deadly target, will they burn the world together, or destroy each other first?
