Worse Than Enemies by J.L. Beck

The first time we met, it was an accident.
The second was the night my mother told me she was marrying his father.
I didn’t know his name then, but I do now.
Hayes Ambrose.
Captain of the swim team.
Popular, gorgeous, the guy every girl wants, with a smile that’s hiding a million secrets.
In the beginning I was certain we would become fast friends, until the day I heard a conversation that I was never supposed to hear.
Overnight he became my worst nightmare, my bully.
He’ll do anything to keep me quiet, and I’ll do anything to discover the truth.
Until the truth is revealed and I realize it’s far more terrifying than I ever expected.
