They say opposites attract. Luca never believed that. She'd much rather spend her afternoons identifying rock samples, watching clouds drift across the Iowa sky, or trading insults with her three older brothers than getting involved with Briar University's star quarterback. Beau Maxwell, on the other hand, is exactly the kind of guy she avoids. Confident. Charming. And with a reputation that speaks for itself. When an unlikely friendship begins over sarcastic banter, impossible questions, and a completely unofficial jury of rocks, neither of them expects it to become anything more.
