Boy, did I love Last Call: A Novel.But then, that should be no surprise -- an urban fantasy novel that incorporates ancient mythology, the Mob, Arthurian elements (including my beloved Fisher King), Tarot cards, mythic archetypes, and allusions to and quotations from "The Wasteland" by T.S. Eliot (my favorite poet) is pretty much guaranteed to please me. Better yet, Powers is a great writer, whose prose is rich with symbolism and allusions to art, pop culture, history, and mythology.
The story itself is about Scott Crane, a retired poker player who realizes he unwittingly sold his soul years ago to a man determined to live forever. Scott's plan to win back his soul becomes entangled in a magical power struggle as various factions vie to become the new King of the West. Powers has a wonderful way of mixing together historical events and figures, oddball fictional characters, and inventive magic to create a narrative with real weight.
I also recommend:
American Godsby Neil Gaiman, which has much in common thematically with Last Call.
The Anubis Gates,also by Powers.
