The Last Straw [EPUB ebook] 

When a teenage girl witnesses a carjacking gone bad, she is marked for death by a crime boss.
A lawyer and an enforcer forge an uneasy alliance to protect the girl from a hit man with an agenda of his own. Soon after, Paul Elliott – lawyer and close friend of the witness’s family – begins counseling them and becomes entangled in the murder plot.
As the long-simmering feud between Rico – the white enforcer – and the hitman John D’Angelo reaches boiling point, bodies start to pile up in rapid succession… and old scores will be settled.
