Her boyfriend's older brother should be off-limits, but he's a sinful temptation.

Sarah is a preacher's daughter and a people pleaser. She's also on the verge of graduating high school and following her dream of singing in Nashville. The only thing standing in her way is that the entire town of Devil's Head, Missouri, thinks she will marry Matt, the son of the town's richest rancher.

But Sarah's not sure he's her future husband, especially when his older brother, Isaac, returns home after serving six years in the Army. He has tattoos on his arms and bad habits that are not "father-approved."

When he's not working on the ranch or roping at the rodeo, Isaac hangs out in the barn, playing his guitar. He's trouble, but Sarah's music-loving heart gravitates toward him.

Isaac loves consuming Sarah's mind, crawling under her skin, backing her into corners, and whispering inappropriate things in her innocent ears.

After weeks of playful banter and guitar lessons blurring the line between right and wrong, Issac makes Sarah a proposition she can't refuse.

But when the unthinkable happens, and everything she knows is destroyed, will Sarah make the right choice?
