Merciless Monster (Deadly Entanglement Book 1‪)‬

Arturo Abruzzi tore the world apart to find the woman that he loved, who mysteriously disappeared without a trace.
Feeling empty without her.
Cold.
Numb.
Hollow.
Feeling like he was better off dead.
Better off six feet under the fucking ground.
And there were times when he would provoke his assassin to pull the damn trigger.
Wishing that his suffering would be put to an end.
Asking God to drag him straight to hell.
After all, hell was the resting place for criminals like him, wasn't it?
The final destination for Mafia men?
But years later, fate caused their paths to collide again.
To cross again.
Except this time, she was married to someone else...

Book 1 of a trilogy, ends in a cliffhanger
