Ghosts, accidental time-travel, a secret clan of immortals, and Maxwell's Demon are all subjects in this complete collection of short stories by Tim Powers. Elusive and evocative, these stories are excursions into strange and dangerous worlds and are as colorful and inventive as Powers's novels. A pioneer of the popular "Steampunk" genre of speculative fiction, his complex and tightly researched "secret histories" blend with compelling fantastical elements to create some of today's most memorable modern science fiction.
