Don't worry about what Dennis Monk did when he was drinking. He's sober now, ready to rejoin the world of leases and paychecks, reciprocal friendships and healthy romances--if only the world would agree to take him back. When his working-stiff parents kick him out of their suburban home, mere months into his frangible sobriety, the 26-year-old spends his first dry summer couch surfing through South Philadelphia, struggling to find a place for himself in the throng of adulthood.
