For one to succeed, the other must die.

After his father is murdered by the fae, orphaned Cinder pledges his life to the Vowed, using his skill with a blade to become Fae's Bane. But when word of a price upon his head and the chance of war arise from the mythical Fae Queen, Cinder searches for a way to keep the kingdom, and his found family, safe.

Kasia, princess of Tairia, has not been sent to Reoria in pursuit of a husband as rumored. Heir to the Fae Queen, she is tasked with discovering the identity of Fae's Bane, for only his blood will bring down the veil between the fae and human realms. Delivering Fae's Bane to her mother is her only chance to prove that she is fit to rule, and Kasia believes Cinder may be the key to helping her find this elusive fae hunter.

When secrets are revealed and hearts are betrayed, two mortal enemies must choose between love and survival, before their world is destroyed forever.
