His Cold Blue Command by A.J. Downey

Assistant District Attorney Damien Parnell leads a double life above and beyond his membership with the Indigo Knights. Driven by dark desires considered shameful by most, he covets the one thing he can’t allow himself to have – a real relationship.
Enter Ally Blaylock, an innocent by Yale’s standards. She’s the sweet and beautiful girl who makes his coffee at the café across the street from his office. She’s done her best to flirt off and on with the high powered attorney and he can’t help but be drawn to her whimsical charm.
When Ally finds her world tipped on its axis, Yale goes against his better judgment and offers her some unlikely help. He knows better than most that the road to hell is paved with good intentions, but in this particular case, could it be the opposite? Could Allison Blaylock be the start down the road to his salvation?
