Rainbows End is a 2006 science fiction novel by Vernor Vinge. It was awarded the 2007 Hugo Award for Best Novel. The book is set in San Diego, California, in 2025, in a variation of the fictional world Vinge explored in his 2002 Hugo-winning novella "Fast Times at Fairmont High" and 2004's "Synthetic Serendipity". Vinge had tentative plans for a sequel, picking up some of the loose threads left at the end of the novel. The many technological advances depicted in the novel suggest that the world is undergoing ever-increasing change, following the technological singularity, a recurring subject in Vinge's fiction and nonfiction writing.
