Re: can anyone recommend any tos books
I don't really enjoy the TOS era novels as much as the 24th century books, but out of the recent ones I'd say try Allegiance in Exile and The Shocks of Adversity which are both very good - especially Shocks. Devils Bargain and The Weight of Worlds are also enjoyable in a very 'episodey' way.
I can't think of any others I've liked recently (I'm not counting the Dept of Temporal Investigations books).
