For nearly 150 years, werewolf Kiyo has wandered the planet as a lost soul. Cursed with immortality, he spends eternity as a mercenary for hire. When the powerful Fionn Mór confides the truth about the existence of Faerie and hires Kiyo to protect one of the fae-borne, he accepts the challenge. If Kiyo is to succeed, he must help Niamh find herself again, and not just for her sake. Ignoring the connection between them may no longer be an option. A new enemy is rising and threatening to rip open the gate between worlds. To remind Niamh of who she really is, Kiyo must make the choice to lower his defenses and give into their bond. Or safeguard his own heart…and in doing so lead the human world to the brink of war.
