An impressive debut from Ritter, with a sardonic and likable protagonist and a whole lot of moody atmosphere. I got goosebumps occasionally, making realizations along with Abby Williams (a name that must have been intentionally chosen, given the storyline about high school girls with a hysterical/fake illness) . There's lots of layers to the novel, that left me thinking for some time afterwards about it. But, it's also enjoyable and page-turner on the surface. The end left me a little cool; there was resolution but maybe I was just disappointed to say goodbye to Abby.
