Fatal Fandom by Jake Helgren

3.70

When famous pop star Eden Chase is almost kidnapped by a crazed fan, she enlists the help of handsome, brooding bodyguard Jackson Reed to move into her home and become her security full-time. But when Jackson develops an unhealthy attachment to Eden, she soon realizes the man she’d called her protector–has now become a predator harboring a dark secret from the past–and that she must outwit him or become prey.
