"The World Wreckers" is awful. Plain and simple. Now, I'm a die-hard Marion Zimmer Bradley fan, so this is not an easy thing to say. Take my word for it -- this is a BAD BOOK.Why? The plot is inane. Basically, some evil scum developers come to the invented planet of Darkover with the intention of exploiting its people and antural resources. The aristocracy of the planet jumps into action, and the author seems to forget their previous indifference to the well-being of the peons.Why else? The characters are better described as caricatures -- always seen by the reader as stereotypes and extremes. The writing itself is confusing, unstructured, and full of grammatical errors. The book lacks originality, and reads like every other science fiction pulp ever written. Even if you love the Darkover series, skip this one.
