Her Mercy - River Reapers MC, #2.5

The last time Bree ran away, she put the love of her life Mercy in prison. Now that he's out, he's got to find her and convince her they belong together so they can both be free. Bree has been running for decades. Every time she gets into trouble, the River Reapers MC covers her tracks. That's how she met Mercy, the only man who's ever loved her, and the reason she's running again. Mercy has an ache in his bones that not even freedom can soothe.
When Bree disappeared, she put him in prison both metaphorically and physically. Mercy needs to find Bree and reclaim the home they once found in each other. But Bree is still buckling under the weight of her own prison, and if Mercy doesn't find her before her past does, she'll disappear forever. Her Mercy is a second chance, age gap, dark romance and is a prequel to the River Reapers MC series.
