Lux Flynn is in a rut. All her life, she's only ever been with one boy and he's her first love. But one summer, with that said boy gone, she's left vulnerable and makes what she deems the worst mistake ever. What's worse is that the boy is her boyfriend's very own brother! She avoided him all school year but now she must go across the country with him on a road trip to visit their future college. Can she resist him, the charming Armand St. Claire? And if she doesn't and falls to temptation, how will she do it without hurting her love, Beau? One thing's for sure, this road trip isn't going to be just about college anymore.
