Query: Very uneven, slow paced start of the series.

"The Invaders Plan" is the first of ten books in Hubbard's "Mission Earth" series. The books were not written separately, but as one long novel and divided into ten parts for publishing. And it shows. The plot moves very slowly, and the entire book is just really a very long buildup. They don't leave for Earth until on the very last page, so don't expect there to be any space adventures of invasion of Earth. I guess that will be in the sequels.The book does have its good parts, and occasional humor, but the pace is very uneven. At times, there are several pages of descriptions of details that are completely irrelevant.If you're just looking for a science fiction novel, look elsewhere. The book does not work well on its own. You must be prepared to read the whole series. If it will be worthwhile reading all ~4000 pages, I don't know yet.
