She knew the assignment would be dangerous. She didn't know it would change her life.

Detective Katie McGrady has trained for every situation imaginable-but nothing prepares her for going undercover as Nicole Moore, a hardened woman with a fake rap sheet and a chip on her shoulder. Her mission: infiltrate the Steel Saints Motorcycle Club and get close to the DiAngelo crime family. Her rules: don't break character, don't trust anyone, and definitely don't fall in love.

Then she meets them-Dalton and Maverick. Two brothers. One's all Southern charm and quiet strength. The other is fire, fury, and untamed loyalty. Both see through her walls, and both threaten to burn down everything she's built to protect.

As Katie navigates a world of roaring engines, buried secrets, and found family, the lines between right and wrong blur-and so does the line between who she's pretending to be and who she truly is. But danger is closing in fast, and the deeper she falls, the harder it will be to walk away.

Riding the Line is a high-stakes, emotionally charged romantic suspense with morally gray heroes, a badass heroine torn between duty and desire, and the kind of found family that fights for their own-no matter the cost.
