This was a very fun read with a nice, twisty meta thingy. And it's timey-wimey, too! I am just glad I watched Star Trek TOS before reading this, otherwise I might never have understood why the narrative worked that way. No more can be said without spoilering everything. I wonder though why Jenkins was named Jenkins, it does remind me of a totally different area of pop-culture.

PS: it's a quick read, I finished it in two evenings.
