I believe I read somewhere that it's better to read Sword of Damocles before Greater Than The Sum, but I don't remember where I read that and why it was better in this order. Is it true or it doesn't matter? I checked on 'The Reading Order Flowchart from Thrawn and 8of5 and the two books are at the same level. So what is your advise?
I don't believe there are any instances where reading ST novels in order of their publication
spoils anything. That's the order that avid readers-who-are-caught-up-on-everything read them, after all. Using the publication dates (behind the title page) only gets tricky if you're reading a MMPB reprint of a hardcover or trade, or a hardcopy version of one of the debut-in-eBook tales.
