During the Flight by Emma Alcott

They say joining the Army changes a man… too bad Chris never got the memo.

Sure, his battle-sculpted body and brooding blue eyes are hotter than asphalt in summer, but he’s still every bit the jerk he was before leaving their small town for the military years ago. Pompous. Arrogant. Cocky as hell… and constantly on Warren’s mind.
It should be easy to ignore him. Straight single dads aren’t worth pining over, and straight a*holes even less. If only Warren could stop dreaming about the way it would feel if Chris were to grab him by the hair, rake his teeth down his neck, and—well, you get the point.
The problem is, Warren’s fantasies aren’t likely to dry up, because something about Chris did change while he was away… and the glint of desire in his eyes when he argues with Warren now? There’s nothing straight about that.
