Stick Work by Cathryn Fox

Sharing a house—and a Jack-and-Jill bathroom—with my brother’s best friend is a special kind of torture. Especially when that man is the one I’ve secretly wanted for years.
But pretending to be his girlfriend at a family gathering? That’s a whole new level of agony. The stolen glances, the whispered questions, the charade—it’s all to get his parents off his back.
It’s fun and games… until I have to share his bed. Close enough to feel his heat, yet miles from what I truly want. It’s an exquisite kind of punishment.
And then Vegas happens. A wedding, a reckless moment, and a single choice that sets off a chain reaction capable of destroying everything: my brother’s trust, his family’s belief in me, and most painfully, my own fragile heart.
