ATF Agent Sam Dean is missing, and Mason Younger steps out of the shadows – landing right in the middle of the Six-gun Outlaw motorcycle club and the James family. In the outlaw underworld, Mace’s past in the Marine Corps Second Force Recon impresses the MC President, Alan ‘Stone’ James, quickly sending him up the ranks. His expertise in weapons, sharpshooting, and hand-to-hand combat makes Mace an asset when it comes to the club’s illegal gun selling. This allows him to take part in jobs that prospects never get to see. But this prospect needs to go deeper. This prospect needs actual access to the MC’s gun sales. What the SOMC doesn’t know is that a patched member ratted out the club brothers and is providing all of the intel to build Mace’s cover. Everything is falling into place and going according to plan. After three long years, the end is finally drawing near. That is until a chance encounter with Amethyst James sends Mace reeling. As an intense relationship begins to boil, Mace struggles to maintain his undercover identity, expose the traitor within the club, and bring down the MC. With Amy knocking him on his ass, literally, bombs, and an attempted murder, Mace’s sense of reality begins to blur as he strives to fight his rapidly growing feelings for her and the new loyalty to his brothers.

Seven months after the death of SixGun Outlaw member Alan "Stone" James, the motorcycle club is trying to rebuild their lives and learn how to go on without their president, friend, and family member. But moving on isn't as easy for Espina "Thorne" Lopez after having lost her sister. Content to spend her days alone, beating up a punching bag and wallowing in her grief, no one has seen Thorne since. Until she's called in for a favor involving her partner's brother. Dalton "Apollo" Kilpatrick is arrested for something he didn't do, but no one believes him. So the judge puts him on a three month house arrest in the home of the last person who wants him. Will they get along, or will she be a Thorne in his side? Apollo is a handsome man that women can't deny - some would go as far as to call him beautiful. Thorne considers herself a monster - a beast for not being able to stop what happened to her sister. So ... "Why not put the beauty with the beast" and see what happens? Can Dalton repair the crack in her heart before the last petal falls?
