From acclaimed science fiction author Brian Stableford (Year Zero, Designer Genes: Tales from the Biotech Revolution) comes the first book in a staggering new trilogy featuring the most incredible backdrop of all—an entire planet. Asgard is a planet-sized artifact presently orbiting a star on the edge of the galaxy. It seems to consist of a series of concentric spheres, each of which was once host to several complex civilizations. Since its discovery by the Tetrax, scavengers from dozens of other species have accumulated in a hastily improvised city, busily scouring the outer layers for artifacts that might offer clues to the advanced technologies involved in the construction of Asgard. One of the few humans involved in this hectic search is Mike Rousseau. Michael must fend off predatory aliens, militant humans, and the rest of the races that are vying to be first into the hollow core of Asgard. But everything changes when he discovers that Asgard is still inhabited by another alien race—and who knows how they will react to the realization that there is an entire outside world above their heads? This is a major revision of 1982 novel Journey to the Center. It was revised for the first time in 1989 for UK edition as Journey to the Centre

Acclaimed science fiction author Brian Stableford (Year Zero, Designer genes) returns with the final book in his trilogy about a planet that contains thousands of worlds inside it—and the one man who will do anything to penetrate its secrets. The conflict between the Isthomi and Scarid races and the surface dwellers of Asgard had come to a halt, but not an end. Forces are at work on all sides to attempt to gain the upper hand in the struggle to control Asgard, for control of Asgard’s heart could mean total power over the planet itself, and all who live in it. At the middle of the struggle is Michael Rousseau, who must penetrate the very core of the planet itself—both in reality and in another dimension altogether—to save Asgard and all who dwell in it, before it’s too late. This is a major revision of 1990 novel The Center Cannot Hold
