As for me, I just finished reading Book 1 - Gods Of Night and I thought it was great.
Of course, there were a couple of things I had questions about in terms of where the characters were compared to where I last saw them. I thought I missed a book or something.
Thankfully over on the Star Trek.com boards, the author of Book 1 David Mack answered my questions.
I bought this over the weekend. Only read the Prologue and the first chapter, but I like it so far.
Then go to the message board section.
Then go to the Books & Products forum.
