I'd like to be able to say "The Medusa Chain will continue...", but it didn't.
Unfortunately, the book (and most of the DC Graphic Novel series) sold poorly, and the project ended after only six issues.
(The exception was Jack Kirby's The Hunger Dogs.)
It was revived a year later as DC Science Fiction Graphic Novel, using adaptations of already-published prose novels by big genre names like Robert Bloch, Harlan Ellison and Ray Bradbury adapted by comics pros like Doug Moench, Keith Giffen and Klaus Janson, but fared equally-poorly, ending after seven issues.
