The early twenty-first century is a time of social breakdown, and the breakdown is being fought (or abetted -- it's not clear) by an uncatchable vigilante who calls himself Mr. Justice. Sometimes he leaves criminals bound and gagged at police stations, with proofs of their crimes. Sometimes he exacts his own retribution. Finally, the Secret Service opts for a long-term solution to the problem: They recruit a twelve-year-old boy with exceptional potential, put him in a school which can enable him to realize that potential, and aim him at Mr. Justice. Years pass, during which Daniel Jordan grows up and starts his hunt, and during which society continues to break down.

A desperate search for the dream planet
Doubleluck...Home...with its streets of flowing gold, waterfalls of diamonds, lakes of perfume - and its deadly curse! Jade is the one human with the will to challenge all odds and find the key to save her species. Fellow creatures fear her ability to dream. The powerful Rulon will exterminate all galactic life unless he can possess both Jade and the riches of Doubleluck. The brutal Dreens seek to mate with her to improve their inferior stock.

It's an Earth on which humans have evolved to the level of gods, and some animals -- notably the descendents of rats -- have evolved to the level of humans. One day something new evolves, or is born, a...soul eater, and it begins seducing people (of various sorts) into becoming part of it.

Four-year-old Reee is the last human on Earth when she is saved by Emeroo. Indigo, who is in the process of eating the world.

She turns out to have brought company with her.

The ability to see the other-dimensional rings that float in Earth's atmosphere was a late mutation of a few space-age humans. Daryl was under the care of the institution for muters, and she had discovered that if you jumped through the ring at the right time it would land you in another dimensional world and another shape. Spaceling is the story of Daryl's desperate efforts to unravel the mystery of why she was being held captive and of what was really going on in a certain alien dimension. Because she was sure it was all bad and that someday everyone would thank her for the revelation. But instead, everyone was engaged in a wild effort to hold her down, to keep her on this Earth, and to keep the world simply intact!

A dystopian novel where another invulnerable monster from somewhere mysterious threatens the gleaming perfect city.

In the far-flung future, humanity has abandoned the over-polluted Earth and settled on a dozen other terraformable worlds, rarely giving the ancestral homeland a second thought. Finally, though, a mission is put together to exfoliate the huge flora and fauna that have grown up over the millennia, making the Earth itself a candidate for custom terraforming at some later point. A two-man expedition is sent to rubber-stamp what the historical record and long-range scans show, i.e., that there’s no human life left on Earth.
Except there is.
