Impostors, Scott Westerfeld, 2018. The first of a new sequel trilogy in the Uglies-verse. Uglies is actually pretty far down in my personal ranking of Westerfeld serieses (Leviathan > Peeps > Midnighters > So Yesterday > Uglies? what am I forgetting here. Oh, Zeroes, if you count co-written stuff, not sure where I want to put those. And I guess So Yesterday isn't actually a series, just a book, and there's Afterworlds, and those Spill Zone comics but I've only read the first one of those. Anyways, I'm not wedded to that ranking of Peeps vs Midnighters or So Yesterday vs Uglies, ranking is hard) but even less-good Westerfeld is still pretty great. I mean, I would *recommend* the Uglies books! Clever high concept, great action writing (especially the train sequences in Extras, as I recall), the spagbol gag, etc. Impostors takes us back to the world some time later, and so far I'm a bit confused as to how what we've seen so far fits in with what I remember from Extras, but there's two more books to go (or maybe I'm misremembering something). I was kind of lukewarm about some of the character beats but there's a few that Really Land, and some good Westerfeldian visuals. I will definitely read the next one.
