I really enjoyed this which is no surprise because Star Trek 4 is my favorite and the best of the trek movies.  The political trouble and environmental beats were fun to read.  Some things I didn't like were how fast the issue was resolved at the end.  And halfway through the book the scientists were disappeared and we never heard from them again. It's still unclear to me that they were found/ rescued? It was odd because they were such a big part of the early half of the book.
