This is the third and final adventure of the legendary Michael Kane (not to be confused with British actor Michael Caine, whose voice people love imitating on late night talk shows). If you've read the previous two novels in the trilogy, you know exactly what to expect. The first half of the book made me think that Moorcock was improving at this type of storytelling, but it turns out he was just saving the really dumb stuff for later.
This series never stops feeling like a rip off of Edgar Rice Burroughs' JOHN CARTER stories, but one can't really complain, since the JOHN CARTER books borrowed so heavily from Edwin Lester Arnold's GULLIVER OF MARS.
There's not much one can say about MASTER'S OF THE PIT. Michael Kane fights the bad guys, gets captured, escapes, fights other bad guys, gets captured, escapes, fights other bad guys, gets captured, escapes...and so on and so forth. It's entertaining enough, but not something you'd go out and recommend. Interestingly, this book attempts to soften Michael Kane's image a bit, as though Moorcock were starting to feel guilty about the level of violence in these tales. At one point in the narrative, Kane insists on abandoning the capital city rather than kill the human zombies that are bent on invading it. Since this is your typical pulp novel, such noble intentions inevitably pay off in the end. Unfortunately, deus ex machinas aren't so common in real life.
