Fair plot overshadowed by repetition
I really don't know how I stuck it out for all 10 books. There is a fair plot and is strongest when in science fiction mode. Then it veers into some shady areas. All the myths of our culture are fair game: pyramids, Area 51, Atlantis, life on Mars, etc. When they ended up in Loch Ness at one point the surprise was that Nessy didn't make an appearance.
The dialog is so lame, repetitive, annoying. The characters are more relatable when there's no talking. One guy, an intelligent man with a college degree, speaks like Festus. I guess because that's how the author imagines rural people all speak. "I reckon" and "ain't " and double negatives along with the constant misuse of "them" as in "them aliens" instead of the aliens or those aliens. He didn't say "them thar" but almost. Seriously, I kept seeing Yosemite Sam when this character had dialog. Ugh! One of the aliens calls everyone "Darling" -- really?
And the same phrases keep repeating (reached out with his/her mind, suddenly, etc.) Then every time there's a meeting he lists everyone, every time.
Anyway, I paid very little for the 10 book series and I was determined to get my money's worth. I feel like it could be reduced to 5 books with half the pages and cleanup the dialog (add some humor, or personality) and the plot would have made it a good series.
