Spirit of Danger by Sidney Bristol

Merida just wants to get through Christmas this year, but after a disastrous day at work and her house flooding, it’s not shaping up to be a great holiday. At least until her neighbor, best friend, and totally-off-limits crush comes to her rescue.
Finley walks a fine line of respecting Merida’s boundaries while lusting over her body. He should have never struck up a friendship with his sassy neighbor. He knew that the moment he first saw her. This Christmas he wants one thing he can’t have: her.
A home disaster quickly spins out of control when Merida is called into work for a strange emergency. Finley can’t shake the feeling that something isn’t right. He’ll stick close to her until the lines are blurred because her body is his to protect.
