An incredibly, and at times exhaustingly, detailed account of the making of the first Star Trek film. If you're the kind of Trekkie/er that enjoys the real-world stories and behind-the-scenes info as much as the in-universe fun (and I definitely fall into that bin), this is well worth reading, and a worthy companion to Marc Cushman's three-volume "These Are the Voyages" series diving into the making of the original series.
