If the name Phil Nowlan is not well-known today, it is because it has been eclipsed by that of his most famous creation, Buck Rogers. Buck began life as Anthony Rogers, in Nowlan's first published story, Armageddon 2419 AD., and its sequel, Airlords of Han, quickly became a phenomenon that popularized science fiction in the first half of the twentieth century in the same way that Star Trek and Star Wars popularized it in the second half. But until now, Nowlan's other science fiction stories have been forgotten in the wake of Buck's immense popularity. Collected here with the original Anthony Rogers stories are The Time Jumpers, The Onslaught from Venus, The Prince of Mars Returns, and Space Guards.
