Logan's World, as the prequel Logan's Run, gets a solid 3.5 from me. Please see my review on Logan's Run, and imagine the word DITTO on just about every thought. Finished this one in about two afternoons, and found it to be entertaining, though still much too brief and stilted to be an all-time favorite.
Logan's World picks up a few years following Run, with trouble on the Sanctuary planet with the disruption of supplies from Earth. As surviving runners begin to die, eventually Logan, Jessica, and their young son are forced to fly back to earth to determine the cause.
What they find is the earth in even worse chaos than when it was being run by computers in the hands of juveniles a few years prior. In a search to discover the causes, Logan and Jessica are subjected to horror, after horror, in the anarchy that followed the fall of the old world.
Enter a new set of barely described characters, jumping from one scene to another so fast you'll lose your small clothes on the turns, and plot development that could balance on the edge of a flint arrowhead. In fact, a few flint arrowheads would have added a lot of interest to this tale of fallen civilization. Instead we're introduced to paravanes, another type of vehicle that flies but we're not told enough about them to figure out what they look like or how they're propelled, to the same guns used in the last book, to long range travel still allowed in a short period of time with no solid explicable way for it to happen.
A few fun jaunts during the ride. Gypsies surface again as devilstick riding, sadistic, Borgias. Without spoiling too much, Logan is separated from Jessica and their son, and terrible things ensue. Once again in this sequel, rape and sexploitation are commonplace. Mary Sue moments are plentiful. Deus Ex Machina rules the day, and Logan cannot be beaten. Perhaps the most amusing deliverance is from Logan's almost sure death by a girl named, believe it or not, Mary-Mary.
Still a fun read, but many, many missed opportunities for description, plot and character development.
