A Thug's Heartbeat by Niya Moore

The streets pump blood through Rocko’s heart, but his women are the electricity that spreads and causes it to contract. Though he’s madly in love with his fiancée, Troi, he can’t keep his past mistakes with other women from catching up with him.

“Mistakes have the power to turn you into something better than you were before.”
 
Troi is tired of his constant lies and cheating ways, while Heather and Mai find that being Rocko’s baby mamas comes with more than they bargained for. Troi discovers that she’s pregnant just when she’s wishing she could shake Rocko for the last time.
 
When things seem as if they can’t get any worse, Rocko discovers he has yet another baby mama who hid his child from him.
Trying his best to stay out of prison for a murder he didn’t commit, he keeps Troi out of harm’s way. While the streets want him, his children, and the women in his life dead, the only thing he wants to do is to marry Troi once and for all. Will Rocko be able to keep everyone safe and change his life for the better? Or will the street jury find him guilty and take everything away?
