The open thread for Symbiont discussion is located right over here.
As always, I have partial comment amnesty—I won't be replying to everything, or even to most things, but you can assume that I will be reading them all. If you want to have a discussion free from the potential for authorial interference, the forum discussion link is here. I will not read the forum topic, so you don't need to worry that I'll suddenly reply to you when you just wanted to chat with other readers.
Thanks for reading, everybody. I couldn't do it without you.
(Comments have been disabled, on account of this isn't the discussion post, and I like to keep all the spoilers in one place.)
