I am a confessed Kar Schroeder fan. His Virga sequence is remarkable – absolutely the kind of retro, yet hyper-advanced concept I love to become immersed in. Engine of Recall is a collection of his short stories from across his career. The worlds Schroeder creates are amazing – ships jousting at near-light-speed, artifacts orbitting pulsars, and so on. I’ve read the first three Virga books, and am looking forward to reading the fourth, and then reading more of his back catalogue.
