In White Night, Wizard/PI Harry Dresden (the hero of the Sci Fi network series) looks into the deaths of local witches and defuses a plot hatched by vampires.
Take your pick: Dresden’s ice queen client, his nubile apprentice, or his leggy ex. Plus, there’s a succubus.
After nine Dresden books, Jim Butcher’s supernatural Chicago holds little mystique, only endless rules and relationships explained ad nauseam in his hero’s irksome inner monologue.
