Shadow Hunt by Misty Evans

He couldn’t save his sister. He won’t fail his sister’s best friend.

FBI Special Agent Claire Dawson has spent her career putting predators behind bars. Now one is hunting her—a stalker whose obsession has escalated from watching to something far more sinister. When the Bureau quietly sends her to a secure location in Montana, she expects protocol and procedure.
What she gets is Garrett Cross.
The former SEAL turned covert operator is everything the FBI isn’t—dangerous, unpredictable, and operating outside every rule she swore to uphold. He’s also infuriatingly protective, devastatingly attractive, and hiding something behind those haunted green eyes.
As the stalker closes in and bodies start dropping, Claire must trust a man who won’t explain why he’s so determined to keep her alive. But Garrett’s secret isn’t just about the mission.
It’s about a promise he made fifteen years ago. To a girl who’s now dead. About the girl she left behind.
Some debts can only be paid in blood. Some promises transcend death. And some men will burn the world down to protect the woman they were always meant to save.
