Ruthless Desires Prequel - Ruthless Desires, #0.5

A sweet barista. Three revenge-bent hitmen. One chance encounter that changes everything. Rhett, Elliot, and Oliver only have one goal: taking down the man who ruined their lives ten years ago. There's little else they focus on except their Friday morning trip to a new coffee shop. There, they meet Wren, a barista questioning whether she should move on from her toxic boyfriend or not. She's kind, sassy, and is the queen of matching energies.
Quickly, the guys realize how refreshing spending time with Wren is. A deep darkness surrounds their lives, and she gives them something they haven't had in a long while: hope. This prequel can be read before or after you finish the series. Whatever you prefer!
