Peter Heck has given Barbarians of the Beyond, the authorized sequel to Jack Vance’s Demon Princes, series a fine review in the latest Asimov’s.

He says:

Hughes puts together a complex plot, full of shady characters and exotic settings, worthy of Vance himself. Little touches—the cuisine of distant worlds, the names of ordinary things, the dance music of a far-future culture—are all reminiscent of Vance’s characteristic world building. And there are occasional side glances at the original Demon Princes novels—subtle hints I might have missed if I hadn’t recently re-read them—that help blend this new novel into the work that inspired it.
