A Lycan descendant of Gilgamesh and Enkidu, Tristan is not as extraordinary as his ancestors. He is an average warrior, unremarkable throughout. But this fact does not trouble him because he has found his Twin Flame, the one person destined to be his, who will love him unconditionally, life after life.

Then his Flame betrays him, leaving him shattered and dying. Brokenhearted, Tristan dissolves the sacred bond and leaves. His best friend, Ushna, accompanies him, vowing to guard and protect him, and Tristan slowly comes to realize that love does not require a sacred bond.

But if he hopes to keep the love he chooses, they will first have to survive ancient secrets, lies, mythical creatures, and the return of absent gods...
