Final invasion was not final
Reviewed in the United States on December 19, 2019
This space soap opera si probably going to go on forever. The opening premise was hopeful and then the next books showed that there was not an end to the story. Each of the books is interesting and moves right along presenting problems to be overcome and imagination by the principals on how to get through them. But just as you think they may be reaching their objectives a new window of challenges appears (or justification for the next book). After 3 I give up and am going on to something more fulfilling.
