I decided to start posting The Altian Plague, volume IV of the Earthbound Series. This story is a bit more hard sci-fi than the first 3 volumes.
It also gives Senta an opportunity to redeem herself, and to find resolution with her relationship with Nykkyo. I am fond of Senta as a character and feel she was somewhat ill-used in the first 3 books, being represented as bit of a starts-with-B-rhymes-with-witch. Despite some personality issues she has a good heart and plenty to contribute.
