I read them when they came out and I remember them being really rather good. I was concerned at first that the Tlaoli IV storyline would get boring, but each of the novel adds a twist. Its a shame that these lower decks novels didn't continue, but I can understand why they were discontinued.
When you've finished The Janus Gate
, check out Errand of Vengeance
if you haven't already. Those books are truly a step up.
Cool! I really am enjoying book 1, which is a happy surprise, TOS is usually hit or miss with me.
By the way, I hope you enjoy the Last Stand. I read it when it came towards the end of High School and thought it was one of the better numbered TNG novels, would love for the author or someone else to pick up the story sometime.
