Query: The first disappointing Shatner Trek book.

I've loved the Trek books, especially Shatner's, but this one was a big disappointment. It reads like 20 chapters plucked out of the middle of a larger book. In a true trilogy, each novel stands on its own. Not so here; Mr. Shatner and his publishers are too obviously milking a "trilogy" for the profits provided by 3 books instead of the one larger book that it really is. I'm annoyed I have to wait for the next book to find out how this story is supposed to end (but I'll buy it, of course).
