The Security Man (Men Made In America 2 Series, #33)
Dixie Browning

Valentine Scott had come back to Lakesboro to begin again. She had a new job, a tiny apartment, a new life. She'd put the past behind her - a bad marriage that had ended abruptly with a terrorist bomb.
She was safe now. No dangers. No uncertainties - and absolutely no Cody Macheris, her intriguing neighbor. Borrowing sugar, okay. Better to stay impersonal though; it was safer. Val couldn't risk loving, and with Cody it was all too tempting.
But Valentine discovered that things change. Past dangers could resurface - and so could long-buried desires.
