I’ve spent my whole damn life making the wrong calls. Not that anyone ever notices—whether on the track or back home, I’m always in the shadow of my perfect big brother. But anonymity has its perks sometimes…like when the firmly off-limits ex of my biggest rival finally looks my way. Chiara Martes—gorgeous, smart, funny, legs just made to wrap around your waist, and a smile that makes my heart race faster than anything. She claims she’s just looking for some fun on the side, and I’m exactly the kind of man who can give it to her. But off-the-charts sexual chemistry (hooking up here, there, everywhere we won’t get caught…and some places we might) turns into unexpected feelings we’ve got to keep secret no matter the cost. And somehow, before we know it, this desperate thing between us is threatening to destroy us all.
