Emma Vaile is the most powerful ghostkeeper in centuries. Which is great for battling the wraith-master Neos and horrible for her social life. Emma knows fellow ghostkeeper Bennett Stern is her soul mate, but when ghostkeepers fall in love, the weaker one loses all power. And until Neos is defeated, Bennett and Emma can't risk it.
When the temptation of being with Emma gets to be too much, Bennett disappears, pursuing a dangerous path to increase his powers. Heartbroken and alone, Emma tries to lose herself in school. But when the Knell, a secret ghostkeeping society, sends two new ghostkeepers to Echo Point—one a snarky teen guy, the other a British scholar—Emma throws herself into training to battle Neos. But as the team grows stronger, so do the ghosts. And worse, one of their own will betray them. One Emma never suspected. . . .
