This was a very enjoyable sci-fi/fantasy. There were a lot of times I wasn't sure what was going on, but I saw the thing with Maera coming from way off! Sometimes when that happens, I can't help but wonder why no one else saw it. Maybe the author hoped to keep us in suspense a while longer before the big reveal, but it wasn't happening for me. Once I have suspicions I have to wonder why other people in the story wouldn't have the same suspicions. Then I loose the believably factor. :-( I have to wonder if this happens to other readers or if it is just me. I am kinda strange that way.Anyway ... The book did have a somewhat final conclusion, but enough things were left open for the continuation of the story.
