Fifteen all-new stories by science fiction's top talents, collected by bestselling author George R. R. Martin and multiple-award winning editor Gardner Dozois Burroughs's A Princess of Mars. Bradbury's The Martian Chronicles. Heinlein's Red Planet. These and so many more inspired generations of readers with a sense that science fiction's greatest wonders did not necessarily lie far in the future or light-years across the galaxy but were to be found right now on a nearby world tantalizingly similar to our own - a red planet that burned like an ember in our night sky …and in our imaginations. This new anthology of fifteen all-original science fiction stories, edited by George R. R. Martin and Gardner Dozois, celebrates the Golden Age of Science Fiction, an era filled with tales of interplanetary colonization and derring-do. Before the advent of powerful telescopes and space probes, our solar system could be imagined as teeming with strange life-forms and ancient civilizations - by no means always friendly to the dominant species of Earth. And of all the planets orbiting that G-class star we call the Sun, none was so steeped in an aura of romantic decadence, thrilling mystery, and gung-ho adventure as Mars. Join such seminal contributors as Michael Moorcock, Mike Resnick, Joe R. Lansdale, S. M. Stirling, Mary Rosenblum, Ian McDonald, Liz Williams, James S. A. Corey, and others in this brilliant retro anthology that turns its back on the cold, all-but-airless Mars of the Mariner probes and instead embraces an older, more welcoming, more exotic Mars: a planet of ancient canals cutting through red deserts studded with the ruined cities of dying races

An anthology of stories Sherlock Holmes is back! Sherlock Holmes, the world’s first-and most famous-consulting detective, came to the world’s attention more than 120 years ago through Sir Arthur Conan Doyle’s novels and stories. But Conan Doyle didn’t reveal all of the Great Detective’s adventures… Here are some of the best Holmes pastiches of the last 30 years, twenty-eight tales of mystery and the imagination detailing Holmes’s further exploits, as told by many of today’s greatest storytellers, including Stephen King, Anne Perry, Anthony Burgess, Neil Gaiman, Naomi Novik, Stephen Baxter, Tanith Lee, Michael Moorcock, and many more. These are the improbable adventures of Sherlock Holmes, where nothing is impossible, and nothing can be ruled out. In these cases, Holmes investigates ghosts, curses, aliens, dinosaurs, shapeshifters, and evil gods. But is it the supernatural, or is there a perfectly rational explanation? You won’t be sure, and neither will Holmes and Watson as they match wits with pirates, assassins, con artists, and criminal masterminds of all stripes, including some familiar foes, such as their old nemesis, Professor Moriarty. In these pages you’ll also find our heroes crossing paths with H. G. Wells, Lewis Carroll, and even Arthur Conan Doyle himself, and you’ll be astounded to learn the truth behind cases previously alluded to by Watson but never before documented until now. These are tales that take us from the familiar quarters at 221B Baker Street to alternate realities, from the gaslit streets of London to the far future and beyond. Whether it’s mystery, fantasy, horror, or science fiction, no puzzle is too challenging for the Great Detective. The game is afoot!

Every short story in this wonderfully varied collection has one thing in common: each features some alteration in history, some divergence from historical reality, which results in a world very different from the one we know today. As well as original stories specially commissioned from bestselling writers such as James Morrow, Stephen Baxter and Ken MacLeod, there are genre classics such as Kim Stanley Robinson’s story of how World War II atomic bomber the Enola Gay, having crashed on a training flight, is replaced by the Lucky Strike with profoundly different consequences
