Adam-Troy Castro has said in interviews that he likes to jump genres and styles and has therefore refused to ever stay in place long enough to permit the unwanted existence of a creature that could be called a "typical" Adam-Troy Castro story. As a result, his short works range from the wild farce of his Vossoff and Nimmitz tales to the grim Nebula nominee "Of a Sweet Slow Dance in the Wake of Temporary Dogs. " His twenty prior books include a nonfiction analysis of the Harry Potter phenomenon, four Spider-Man adventures, and three novels about his interstellar murder investigator, Andrea Cort (including a winner of the Philip K. Dick Award, Emissaries from the Dead). Adam's other award nominations include eight Nebulas, two Hugos, and three Stokers. Adam lives in Florida with his wife, Judi, and three insane cats named Uma Furman, Meow Farrow, and Harley Quinn.
