The Cowboy and the Outcast by Jackie North

Everywhere I go, I look for home. You are my home.
On the run for two years from an abusive family situation, Kell searches for a safe harbor. Instead of that happening, Kell gets arrested, but, unbelievably, amidst the horrors of prison, there shines a glimmer of hope.
Marston’s life is a mess. Everything he touches crumbles to dust. A second chance comes in the form of a job with the Farthingdale Valley New Start Program, except the two parolees assigned to him don’t even show up, so the job is a disaster from the get-go.
Temptation appears to Marston in the form of a particular ex-con: skinny, foul-mouthed, unable to keep up with the other prison-hardened parolees. Now he’s Marston’s responsibility.
Marston has failed at everything else – he knows he’ll fail at resisting temptation.
Can’t sleep. Can’t touch. Can’t have. Kell and Marston are lonely, until they find each other.
Can they make love last?
