The prose was very florid and descriptive unfortunately the story wasn't. It read like the bastard child of the bible, planet of the apes and any number of poorly written fantasy novels. Too many characters whom we know too little about. Whole plotlines conceived then waved away with little more than a phrase. A reliance on magic over science. Pages and pages of "so and so begat so and so who had twins and begat the father of so and so" etc. Really stuff no-one would care about.
Clumsy phrasing such as this gem: "the radiation caused the animals to mutate. Eagles grew as tall as trees"
Just you because you can string enough words together doesn't mean you have to write a book. The acheivment in writing a book is in telling the story not how many words you can pump out. There was no real story to Scorched Earth. It made no sense.
