Devil’s Playground by Maddie Taylor

Pampered mafia princess Carina Denali is running from two men:
one wants her heart, the other wants her dead…
In the wake of her father’s murder, Carina fled her life of luxury. She manages to stay one step ahead of her deranged, duplicitous uncle and Nick Devlin, the gorgeous FBI agent who stole her heart then crushed it. As she struggles to survive and stay out of sight, she soon realizes Nick is her only hope of coming out of her predicament alive.
Nick has been searching for the right woman for a very long time. When Carina turns to him for protection, he knows deep down his search is over. All that remains is keeping her safe from the Mob and winning back her trust for good.
Just as Carina starts to believe a new life with Nick is possible, the vengeful Godfather from her deadly past resurfaces with a chilling demand. There can be no peace, and he won’t rest until more of the family’s blood is spilled.
