Stay by Ash Knight

A quiet coffee shop gives two men who have lost too much a chance at love.
Joe Calloway has been on the run since he was sixteen, homeless and alone. He never lets anyone close. Between his traumatic past and his autism, he isn’t used to people taking the time to understand him.
Even so, when a stranger offers him a way to build a better life for himself, Joe finds the strength to go for it.
Madden Fields is fully devoted to his older sister, her autistic son, and his job as a nurse, but when he meets Joe, his carefully ordered life begins to pick up speed.
As their connection deepens, Madden realizes he’s going to have to hold on tight if he wants to be an anchor strong enough for Joe to stay.
