End of part one. Thoughts so far: I'm enjoying it more than the other Green books I've read to date. Unnecessarily hyphenated phrases are again a thing, most of the teenage boys are displaying varying (but mostly believable) levels of assholeyness, and Margo Roth Spiegelman is one manipulative manic pixie. She reminds me of Gus, only without the stupid unlit cigarette. She's about to disappear, according to the blurb. I'm looking forward to the unfolding of the mystery.
