MUTINY IN SPACE began as a novella entitled "Valentine's Planet," which appeared in the August 1964 issue of Worlds of Tomorrow. "To space opera of the time, the character of the captain was as important as that of the king was to Shakespeare. He (the captain was always a "he," even when the author was female) was the model and exemplar for society, the man with the right stuff, he who made the tough decisions and enforced discipline?

City Under the Stars completes a journey undertaken by Gardner Dozois and Michael Swanwick 25 years ago, when they published the novella The City of God. Over two decades later, the two realized there was more to the story, and began the work of expanding it. Now, after Gardner Dozois' tragic passing, the story can be told in full. God was in his Heaven--which was fifteen miles away, due east. Far in Earth's future, in a post-utopian hell-hole, Hanson works ten solid back-breaking hours a day, shoveling endless mountains of coal, within sight of the iridescent wall that separates what's left of humanity from their gods. One day, after a tragedy of his own making, Hanson leaves the city, not knowing what he will do, or how he will survive in the wilderness without work. He finds himself drawn to the wall, to the elusive promise of God. And when the impossible happens, he steps through, into the city beyond. The impossible was only the beginning.

"Very simply, Tom Purdom IS science fiction. His ever-inventive stories are cut from the cloth of it and sewn with the skill of a master." --Gregory Frost

"Tom Purdom made his first professional sale all the way back in 1957. It's hard to think of any other member of his generation whose current work is frequently mentioned in the same breath with that of writers such as Charles Stross, Greg Egan, and Alastair Reynolds, many of whom were not even born when Tom started his professional career, but Tom's is. In fact, for sweep and audacity of imagination and a wealth of new ideas and dazzling conceptualization, Tom Purdom not only holds his own with the New Young Turks of the '90s and the Oughts, he sometimes surpasses them. And unlike some of today's Hot New Writers, Tom's work never fails to ALSO feature fascinating and psychologically complex characters, and intrepid investigation into the human heart." --Gardner Dozois

"Tom Purdom is the most underrated science fiction writer I know of. His short fiction delivers again and again with great plots, characters, and an imagination both cosmic and delicately complex." --Jeffrey Ford

"Purdom has created a major body of work. Thoughtful, humane, intelligent, extrapolative, involving, his stories are exactly the sort of thing our genre exists to make possible. If you don't like Tom Purdom, you don't like science fiction. Period." --Michael Swanwick

A fantasy masterpiece from a five-time Hugo Award winner

A war-dragon of Babel crashes in the idyllic fields of a post-industrialized Faerie and, dragging himself into the nearest village, declares himself king and makes young Will his lieutenant. Nightly, he crawls inside the young fey's brain to get a measure of what his subjects think. Forced out of his village, Will travels with female centaur soldiers, witnesses the violent clash of giants, and acquires a surrogate daughter, Esme, who has no knowledge of the past and may be immortal.

Evacuated to the Tower of Babel--infinitely high, infinitely vulgar, very much like New York City--Will meets the confidence trickster Nat Whilk. Inside the Dread Tower, Will becomes a hero to the homeless living in the tunnels under the city, rises as an underling to a haint politician, meets his one true love-a high-elven woman he dare not aspire to.
