Mike Callahan runs a bar on Long Island that attracts the kind of clientele most establishments would struggle to accommodate: time travelers, mythological figures, and aliens all feel at home over a drink. Jake Stonebender, a traveling guitarist carrying an old tragedy and a compulsion to help people, has become a fixture. The patrons who drift through Callahan's come with problems that are rarely ordinary: a vampire searching for a love lost across centuries, an alien whose pacifist conscience puts him at odds with his own civilization, and a dire threat to the world's rainforests. Jake takes each one seriously, working his way through a series of conversations, puzzles, and interventions that may or may not be enough to tip the balance toward something better.
