If you are an avid reader of Star Trek fiction then this is the definitive guide. It covers every Star Trek fiction book ever published along with covers and publication dates, number of pages etc. OK admittedly most of this information is available on the internet, but most of it is incomplete or just incorrect, here you can be sure of getting the correct information. For this alone it has been invaluable allowing me to identify those books that I've never read and if that's what you are looking for then look no further. If you are looking for a good read then this is not for you. It is really a reference book to pick up and put down. Also,although a good proportion of the books have plots and author interviews this is by no means complete and if that is what you are looking for I wouldn't bother.
