Kiss the Sky Book by Becca Richie and Krista Ritchie

Rose Calloway thought she had everything under control. At twenty-three, she's a Princeton graduate, an Academic Bowl champion, a fashion designer and the daughter of a Fortune 500 mogul. But not everything comes easy.

When Rose's fashion line is in peril, she plans an unconventional solution to save it. Making matters more intense, she agrees to be in a relationship with her "godly" college rival, Connor Cobalt.
