Asher's Assignment (The Wagner Brigade #5)
Ashley A. Quinn

But when a pregnant Edie comes to him, worried about her sister, Esther, he steps out from behind the screens and heads to Oregon, wanting to keep Edie’s stress levels low. He figures he can install some cameras, do a little investigating and prove to her that she’s worried over nothing. Simple, quick, and clean.
Except he doesn’t count on falling for the smart, soft-hearted kindergarten teacher. Or the fact that he’s now the one in danger.
