So both KSR's Icehenge and Wolfe's Fifth Head are novels made up of interrelated novellas. KSR was, presumably, inspired by Wolfe (being a Wolfe fan, Wolfe's student at Clarion, a fellow contributor to Orbit, and so on and so forth.) My question: can anyone think of any other novels written this way? It seems like a neat form, somehow. The closest I can think of is Joe Haldeman's Forever War , which was made up of, I dunno, maybe five novellas. But of course novels (or at any rate unified works) made up of many short stories are common. Then there's Asimov's Foundation trilogy, where the first volume is composed of short stories, the second & third of two novellas each. Maybe this is a distinction without a difference here, but somehow the three novella structure strikes me as special, just as poems can be written of any length but there's something special about 14 lines (or chamber music for any number of instruments, but something special about 4). So: are there any others?
