Hanging the Stars by Julia McBryant

James used to dream of being a jockey. Now he’s head-over-heels for his gorgeous new boss.
James: I’m in love, but there are three problems.
He owns the stable I ride for.
He just inherited like, a billion dollars.
I’ve had my heart stomped on before.
Maddox inherits a stable full of some of the best racehorses on the East Coast, and I discover my former boss’s son is hot… gay… persistant… and comes with a raging case of ADHD. Maddox has always been short on love and long on social blunders, and he’s learned to hate himself for it. We’re head-over-heels, totally inexperienced, completely in love, and Maddox still can’t understand why I’d bother with him. He says he’s too different.

Then he starts meddling at the track because of me.
Turns out Maddox really is different.
