Chasing After You by E. Baileu

Josh Antley vanished the night everything went wrong.

At eighteen, with blood on his hands and a promise to never return, he ran from the Halbrooke estate, leaving behind the life he’d built with his adoptive family.
Dorian Halbrooke has never stopped looking for him.
Dorian’s life changed the day Josh was brought into his cold, curated world. He was the only warmth Dorian ever knew. His protector. His person. Eight years after the worst night of his life, Dorian is no longer the fragile child Josh left behind. He’s grown, relentless, and willing to burn down the world to find the only man who’s ever dared to run from him.
And this time, he has no plans on ever letting him go.
