Stableford's also written many short stories about the biotechnological revolution in Interzone magazine. The galaxy is full of mysteries. Asgard one of the most inexplicable. Many different species & many types of individual sought answers to its enigmas. Anthropologists, fortune hunters, scientists, gangsters, politicians & explorers found reason to congregate on the planet which possibly wasn't a planet. To stand on the artificial surface & wonder how many subcutaneous levels the planet contained, & what, if anything, was at the center, to examine the artifacts on the reachable levels where the temperature approached absolute zero. Artifacts of a civilization far more advanced than any known spacefaring species of the day. Artifacts of a species who possibly still lived at the center--thousands of miles & levels deeper than any explorer had set foot. The general consensus was that Mike Rousseau, an archeological scavenger might be capable of reaching the center & unraveling the mystery of Asgard. Rousseau didn't agree. Unfortunately, the choice wasn't his... less

Asgard's not an easy world to get away from. Mike Rousseau only wants to take a vacation in his home system, but he's back before he has time to draw breath, and he's been drafted into the Space Force once again. His new mission is even more dangerous than the last one, the number of his enemies has increased vastly, and his friends haven't improved at all... moreAsgard's not an easy world to get away from. Mike Rousseau only wants to take a vacation in his home system, but he's back before he has time to draw breath, and he's been drafted into the Space Force once again. His new mission is even more dangerous than the last one, the number of his enemies has increased vastly, and his friends haven't improved at all. By way of compensation, he has another chance to get closer to the mystery at Asgard's heart--but the inhabitants of the megaplanet's core are no longer content to sit quietly and wait to be found. They've discovered the outside universe, and are trying to decide what to do about it--but they have problems of their own. Only Rousseau can cross the boundaries between species, and offer each of the races a possible solution. Another great entry into an exciting SF series! less

The gods of Asgard are in deep trouble. If they cant defeat their internal enemies, the starlet in the macroworlds core will blow up, killing trillions humanoids in its various layers. Only one man can save this articifial planet, and he can only do that by duplicating himself... moreThe gods of Asgard are in deep trouble. If they cant defeat their internal enemies, the starlet in the macroworlds core will blow up, killing trillions humanoids in its various layers. Only one man can save this articifial planet, and he can only do that by duplicating himself. Unfortunately, the software version of himself that's trying to operate within Asgards virtual space is fighting on the adversarys home ground, and seems to have even less chance of success than the flesh-and-blood version. Even if they both get through, and contrive somehow to save the macroworld from destruction, how can they ever get together again to become a whole man--and at what cost? The thrilling conclusion to a magnificent sci-fi saga! less
