Getaway Girl by Tessa Bailey

This unlikely getaway driver never expected to help the mayor escape… After a six-year absence, Addison Potts is back in Charleston to stir things up. And what better place to make her villainous return than her estranged cousin’s wedding? Only, the nuptials hit a snag when the bride doesn’t show, leaving Addison to play getaway driver for the jilted groom. A groom whose heartbreaking smile and deep, southern drawl she should not be noticing…

Elijah Montgomery Du Pont is the future mayor of Charleston. From his military career to city hall, every detail of his life has been meticulously planned. Until now. His only respite from life’s sudden upheaval is Addison, his new, improbable best friend. She makes him happy. Grounds him. And public disapproval be damned, he’s not willing to give her up. But with an election on the line and public pressure rising, Addison—and the cruel hand of fate—might not give him a choice.
