Hold Him Like Gravity by Jessica Gadziala

Rico didn’t get to be a mafia capo by trusting easily, but he never expected his newest employee, Kick, to be a threat. The meat shop he runs is a perfect front to launder the family’s money, but when a violent robbery leaves Kick hurt and shaken, Rico’s control begins to slip. Drawn by a need to protect her, he finds himself opening up in ways he’s never dared—and growing close to the one person who could ruin everything.
Kick just wanted a fresh start, a simple job far from the shadows of her past. But the night of the robbery changes everything. Because she couldn’t tell Rico every detail.
