Book excerpt: A guided tour though the many worlds of a New York Times best-selling master of authentic science fact and riveting science fiction. James P. Hogan stands among the foremost writers of science fiction today, and is renowned for his ability to combine accurate science from the cutting edge of present-day research with living, breathing characters in fast-paced, suspenseful stories. Catastrophes, Chaos & Convolutions gives Hogan's thousands of avid readers both a solid-chunk of high-quality science fiction and a look behind the scenes, as Hogan describes how his work came to be written, with biographical details. Add a dash of science fact articles, often on controversial topics (suppose, for example, that Velikovsky was right and the orthodox scientists wrong), and you have a volume that is an essential purchase for Hogan fans everywhere. At the publisher's request, this title is sold without DRM (Digital Rights Management).
