The Breakers Series: Books 4-6

I quickly consumed and enjoyed the first 3 books in the Breakers series. I decided to read on, and purchased books 4 - 6 as a set. I just finished book 4, Reapers. The good news: The book was as engaging as the first 3 books, and I read it quickly. Reapers was structured like books 1 - 3 in that there were 2 suspenseful story lines, which alternated chapter-by-chapter. And, as usual, each chapter had a cliff-hanger ending, which kept me reading. The bad news: This book does absolutely nothing to advance the story-line of books 1 - 3. This bait-and-switch ploy really put me off, as it has many other reviewers (wish I had read the reviews before buying books 4 - 6). I expected a continuation of books 1 - 3, and got nothing of the sort. I got sucked in by the earlier books, only to find in Reapers nothing for which I paid. I cannot imagine the thought process of the author, his agent, or the publishers which resulted in plugging this unrelated book into the middle of an otherwise good series. Doing so put me off to the point I may stop reading what Mr. Robertson writes. To be fair, the aliens are mentioned in a paragraph or two deep into the book, but their insertion into the plot is contrived and weak. It is as though Mr. Robertson composed this book as a stand-alone, but figured to get some mileage out of his work but tacking it on to Breakers. Not sure what books 5 and 6 hold, but, since I paid for them, I will at least start 5 to see of Mr. Robertson can again find the target and redeem himself.
