Emperor Mollusc is a warlord and war criminal, wanted throughout the solar system for his unspeakable doings. Throughout the solar system, that is, except for Earth, where he is ex-planetary overlord and just trying to enjoy a quiet retirement. Fat chance of that when the Venusians come calling. Oddly, though, they don't want to kill him, just to keep him safe so that he can (eventually) face justice.
In the meantime, Mollusc has to negotiate a roller coaster of an adventure as he crosses tentacles with the eponymous Brain, which leads him from peril to greater peril. But what does the Brain want, and how does it know Mollusc so well?
Martinez creates a breathtaking (and hilarious) alternate universe where every planet is populated (and most of the residents despise Mollusc) and Earth teems with strange cultures which include Atlantis, a desert kingdom ruled by a deathless queen and a strange, sub-Antarctic world. The pace never lets up, and for the most part the book is great fun - perhaps reminiscent of "Doctor Who" at its most zany. A nice SF themed counterpart to Chasing The Moon wbhich did similar things with horror.
Emperor Mollusk versus The Sinister Brain is a funny and enjoyable read. It reminded me of a Sunday morning cartoon in many ways. The structure is quite episodic, with a over arching plot. All in all I enjoyed the read.
