Guarded Secrets by Diane Benefiel

Everyone in the mountain town of Sisters, California loves Keeley. Or do they?

When she’s attacked, and a woman she knows is murdered, the one person in her life who acts like he can barely tolerate her, swoops in to become her avenger.
A bossy, overbearing avenger.
Keeley should be used to Owen mood swings, but now he’s ratcheted it up to a new level, and she’s not amused. She’s been taking care of herself for years, and doesn’t need him managing her life.
But, there’s this little problem. With him around all the time, how will she quash the Owen crush she’s been harboring for far too long?
Owen figures he can protect Keeley, find and deal with the person who’s trying to ruin her life, and then return to his solitary existence. But the woman is pure mountain sunshine, and keeping her safe means keeping her close, and that risks exposing his heart to the greatest danger he’s ever faced.
