Sephirot

Duncan Kyle is an ordinary twenty-something whose simple life of sports, his job, and his girlfriend comes to a crashing end late one night when he falls through the floor of his apartment.  He finds himself in Malkuth, a desolate, desiccated world where the only living beings are a sardonic Sphinx and her invisible caretakers, who in this frigid place are drawn to anything that is warm.  He is told by the Sphinx that he will have to make his way through the ten worlds of the Sephirot before he will be able to get back home.
In each world he visits, he has to rely on his wits again and again not only to find his way to the next portal, but simply to stay alive.  Along the way he meets a wild huntress who is torn between making love to Duncan and killing him; an elderly woman who tries to convince him that he has been ill and dreamed the whole thing; a scarlet-robed judge who sentences him to be whipped and then executed for performing evil magic; a kind potter and his daughter who take him in and heal him of his injuries; and a timid, soft-spoken Methodist minister who helps him to survive in a world where hell breaks loose, literally, once the sun goes down.
And in each one, he has to summon the strength to keep going-because if he falls for the snare each world represents, he'll never find his way home.
