This graphic novel has the same artist as previously-mentioned Friends with Boys, but where that one is also written by the artist, this one has Susan Kim and Laurence Klavan as writers.
It's got a great, weird premise: the main characters are underachieving kids whisked off to a camp that's going to make geniuses out of them. But it's clear early that weird things are going on at the camp ... our viewpoint characters are there to replace kids who had something bad happen to them.
I liked how this one ended a lot ... it ends with our main characters not having fully resolved the threat, but prepared to meet it head on in the future. Neat stuff.
