This is the 3rd book in a series. Read the first two before this one otherwise some things won’t make sense. The characters are tied together and the order of events that lead to this story. 

Sloane’s little sister Riley doesn’t disappoint.  They don’t look a like or dress the same but their demeanor and strong personalities are a mirror. The sarcasm isn’t as sharp and her heart isn’t so damaged that she fights her feelings the way her tough big sister, but Riley is just as stubborn, mouthy and loyal.  The mafia ladies have quite a bit of power in this dangerous world without ever pulling a trigger.
