Haunted By Regret (Heaven's Guardians MC 3) by Ashley Lane

Haunted (adjective)- Preoccupied with an emotion, memory, or idea; obsessed. It’s what happens to a man that loses his entire family. The first years that followed their demise were the worst. Determined to inflict even a fraction of my pain onto those responsible, I paid them back the same way they paid me. I was content to live out my days knowing justice was dealt at my hands.

Consumed with rage.
Obsessed with revenge.
Haunted by regret.
Years later, I take in two boys and suddenly it’s no longer only about me.
That’s where she comes in.
A broken nanny who heals us all.
