Welcome Home by Lina Langley

Milo Anscombe is back home after ten years. Everything about him has changed–his name, his appearance and his wealth. In hopes to restore his crumbling hometown, Milo begins a secret real estate project. He wants to get in and out, without revealing that he’s back, all while saving the decrepit city from a long road of poverty.
The operation does not come without risks, though. His current life, his billion-dollar fortune… it’s all built on avoiding Danville, on leaving the life he had as a child behind. When Gabriel Villalobos, a long-forgotten high school classmate, recognizes Milo as little Dylan Culpepper, the chubby-cheeked boy who lived in the trailer park behind the hospital…
Milo knows he needs to do something to stop the word from spreading around town.
Giving Gabriel a job might not be enough, though. The man is chatty and excited to be around him… and a lot more interesting than Milo remembers.
Suddenly, Milo might have a reason to stay home. But he can’t, not when people might discover who he really is. Not when he’s only just discovering it himself… all because of Gabriel.
