The story is now complete. The Sentinel Saga will continue ... When Thom's best friend goes missing in the lake in the middle of Juniperville, the townsfolk are out for blood. Thom is the only one who knows about the creature who came out of the lake, who shape-shifted into the young woman who abducted his friend. Seeking answers, he travels to Scotland, where he is invited to join the Modern Folklore Investigation Team (MFIT) as an intern. As he gets closer to an objective truth about the nature and intentions of water beasts, he learns that he has a rare and special power, one with the potential to bring back his friend from the deep. The only one who knows about Thom's power is his MFIT colleague Ondine, who has a secret of her own - one she has repressed for years. Even as Ondine urges Thom back to Juniperville to a reckoning with whatever it was that stole his friend, she realizes that she, too, must face up to the truth of her legacy, and its power.
