New York Times bestselling author Samantha Young writing as S. Young.

Niamh Farren has been burdened by knowledge for most of her life. As one of seven fae children born into the human world with the ability to open the gate to Faerie, Niamh's mission is to guide her fae brethren to do what's right. Because Niamh has seen what will happen to the human world if she does not protect the gate. Throughout the years, she's traveled the world with her brother Ronan, using her psychic visions to find the fae-borne and convince them to stay on the path that will keep the gate from opening. She has sacrificed much ... but when she loses her brother to the mission, Niamh begins to lose herself.

For nearly one hundred and fifty years, werewolf Kiyo has wandered the planet as a lost soul. Cursed with immortality, he spends his awful 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 out of boredom, not heroism. Yet Niamh is unexpected in every way the werewolf can possibly imagine.

Guarding Niamh from her enemies is nowhere near as challenging as protecting the fae woman from herself. If Kiyo is to succeed, he must help Niamh find herself again, and not just for her sake. Ignoring the fierce 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.
