His Regret by Bella J.

When it comes to women, Hunter has rules.

Those rules ensure his life stays uncomplicated and controlled. Control is what he craves, what he needs to keep his inner demons quiet.
Private investigator by day, his life is nothing but a pit of regret, devoid of any and every emotion.
Hired to find an elusive runaway—a wild, hot-headed woman with sinfully enticing curves—Hunter’s self-control is pushed to the limit. Scarlet Woods challenges him in ways that have him wanting to break his own damn rules.
But she has secrets—secrets he’s determined to uncover. He just didn’t count on getting his own past dragged into what turns out to already be a deadly game of lies.

This is not a love story. This is not a tale of how love conquers all.
This is a story of how two people equally shattered by their pasts realize that two broken souls can’t make a whole.
