Aaron ‘don’t ever call me Fatbaby’ Sims is lucky to be alive. Or at least that is what everyone keeps telling him. He doesn’t feel lucky, though.
He’s scarred, has more than a little bit of a bad attitude, and there isn’t a single day that goes by that he doesn’t wish his wife would’ve just finished off the job.

After being denied his old position at the fire department, he leaves, and doesn’t look back. He heads straight to Alabama and into the semi-welcoming arms of The Dixie Wardens MC. There he becomes a part of a brotherhood that forces him to get back in the land of the living.

Imogen is a smart girl. A girl who doesn’t always make the best decisions.

Her heart is in the right place when she walks into that prison, but it doesn’t take long for her to realize that her heart shouldn’t have had any say so in the matter. Especially when one wrong move lands her in the arms of a scarred man that looks frightening enough to scare any sane woman away.
Immediately enthralled by the angry man, she tries to get closer to him. But the harder she tries to get to know him, the further he pushes her away.

The only thing Aaron wanted to do after his now ex-wife was sent to jail was escape. Escape the awful memories. The pity-filled eyes. The curious glances.

He does a damn fine job at ensuring he draws as little as attention as possible, but then that annoying woman with her startling blue eyes starts hammering away at his resolve. Makes him feel when he doesn’t want to feel.

Imogen comes into his life and carves out a place for herself, obliterating his defenses one heated kiss at a time.
