Buckeye and the Babe by Olivia Gaines

Cabrina Roberts flew to Las Vegas to have a face to face conversation and get a possible lead on her friend, Aisha Miller’s disappearance. What she finds instead is Gabriel Neary, codename Buckeye, a CIA Agent that is too handsome for his own good.
Add in two free tickets to a hypnotist show, a bottle of cheap champagne and the pair wakes up the next morning to find themselves married.
Throw in a road trip to Georgia, loads of laughs, and a couple who are simply too perfect for each other to ignore, Buckeye and his babe, begin a not so traditional romance across the miles.
