The book consists of segments from multiple variations of the time stream.
Each "chapter" is from a slightly different version of reality, which explains details like the about-face of Green Taylor Simms's notes from "Let's talk about time traveling and spoilery stuff" to "Anyone who says you can time travel and do spoilery stuff is a whackjob", and the absence of Echo Lawrence from Chapter 42's list of contributors.
