I completely adored the book previous to this one, Planetfall, and it's so wonderful to see the second meet the same impossible standards. After Atlas is not a sequel so much as a companion novel, and I suspect it could be read as a standalone.
(P.S. There will be spoilers for the Divergent series by Veronica Roth in this discussion. You have officially been warned.)
Perfection is abundant in YA, or at least at first glance, it seems so. There is always the stunningly handsome love interest who is somehow smart, funny, popular, and well, perfect. There is always the "flawed" main character who can ace her classes, fight monsters, all while still getting the boyfriend at the end. Perfection has become a standard in YA, and one of my favorite book series is a major culprit.
