True For You (Boys of the South #3) by Marquita Valentine

Jackson
For me, failure has never been an option, not with Everett Morgan controlling my entire career. But when my efforts to win back the girl who got away end up with me helping my rival, I concede defeat—and sneak away to a private island off the coast of South Carolina to lick my wounds.
Only I wasn’t counting on the seamstress for the band driving the getaway car. Or waking up the next day, with Bliss in my bed and a ring on her finger…and absolutely no memory of the wedding.
Bliss terrifies me while giving me hope that I can be more, that I can be this guy no one else can see but her. But I’m not sure who I want to be…except free.

Bliss
I may not have finished high school, but I graduated with honors from the school of hard knocks. Four years ago, after barely surviving the second most terrifying ordeal of my life, I ran away from my foster parents and never looked back.
With one reckless decision, I wind up married to Jaxon Hunter, country music’s biggest bad boy. Only to me, he’s Jackson Morgan, equal parts sweet and selfish, thoughtful and prideful…arrogant and humble. And try as I might not to, I’m falling in love with him.
Only a future with Jackson can’t happen without reconciling with his past. But I’m not sure if I can endure the drama, the secrets… or competing with the only woman Jackson has ever loved.
