Molly Kate Kestner is a high school senior in Austin, Minn. who's uploaded singing videos for a couple of years on YouTube. She started with mostly covers, but she's added a few originals lately. Expect more because her upload last week, "His Daughter," has become a viral smash hit.

In "His Daughter," Kestner tells the all too familiar story of a teenage girl who grew up with an abusive father and later turned to men to fill the painful emptiness in her life. In her darkest hours, she cries out to God.

The spiritual nature of the song looks to be familiar territory for Kestner. In her Twitter bio, she says, "Music is my heart, Jesus is my rock and Breadsticks are my favorite."

The song has resonated with viewers, racking up over 1.5 million views in a week and a half.
