Rival Hearts by W. Million

Maggie
I thought I knew Grady Castillo once upon a time. He was the boy that would never be mine, my ex boyfriend’s older brother. Now the world knows his name and sings his songs. He isn’t the boy who left me without a word anymore.
I never expected him to come home to our small town again, especially not during a girl’s karaoke night. But Grady’s in this bar singing a song I know he wrote about me.

Grady
I never should have touched Maggie, but I did. She was always my little brother’s. Smart, never a hair out of place, and too good for everyone around her–not much has changed.
When my life shattered, she came out unscathed. Time hasn’t changed a thing.
I’m drawn to her like a moth to flame, begging to get burned.
