Lost Boy by Beau Brown

Omega Jesse has a heartbreaking secret. Something so dark and painful, two years ago it made him run from his best friend, turned lover, Baker. But being away from Baker was too painful, and now he’s back, and asking for forgiveness.
Alpha Baker has worked on The Tumbleweed Ranch much of his life. He was crushed when Jesse left and froze him out of his life completely. He’s done his best to move on, but no one touches his heart the way Jesse did.
When Jesse returns, Baker tries to ignore him. He can’t, and won’t, forgive Jesse for betraying his love all those years ago. But ignoring someone who you thought was your soulmate is easier said than done.
