Black God's Drum by P. Djeli Clark is an ornate account of an alternative America around the time of the Civil War. This is pure steampunk set in the deep south; a multi-cultural literary jambalaya composed of opposing religions, shoot-outs on the streets, hot politics, and African magic. A young black woman becomes the tool of warring gods and that just the start of the conflicts.
The author paints a complex mosaic filled with memorable characters and situations. This is a notable example of world-building with a finely tuned imagination and historical palette.
