I’m supposed to keep my distance. He’s supposed to marry my sister. Which makes wanting him the worst idea I’ve ever had.
 
Mason Cartwright is engaged to my sister. That should make him untouchable. Off-limits. Practically radioactive.
 
But the way he looks at me makes my pulse trip over itself, and that smirk? Trouble, plain and simple.
 
The problem is, I’ve never been any good at staying out of trouble.
 
What starts as snarky banter and stolen glances turns into late-night conversations, accidental touches, and a slow burn I can’t seem to put out. My sister’s fiancé isn’t just handsome—he’s infuriatingly charming, annoyingly confident, and far too good at getting under my skin.
 
It’s all part of an arrangement I’m not supposed to know about, but once I do, I can’t stop seeing the cracks in their perfect-couple act.
 
Suddenly, I’m caught between protecting my family’s picture-perfect façade… and wanting the one man who could blow it all apart.
