I'm a bit torn on this one! I really enjoyed The War that Saved My Life. This was augmented by the fact that I read it, coincidentally, right between two very good "grown up" books about The Blitz - Life After Life and Everyone Brave is Forgiven. I felt strongly for Ada, and the author did a great job of revealing her inner turmoil and fears. I did, however, sometimes find her tenacity and cleverness a bit a bit unbelievable. ("I have no concept of grass or trees! But I also just taught myself how to ride a horse in no time at all!") I also really loved the subtle references to Susan's back story, and wanted to know more about her. I agree with other reviewers, however, that the mother was just a bit *too* evil and irredeemable, and the ending was a bit too tidy. (But I was happy! And that's good, too!)
There were many things I liked about The Porcupine of Truth, as well. I appreciated how the author dealt with the realities faced by too many LGBTQ+ youth today, and connected the characters to the historical oppression and struggles of that community. I also appreciated how Konisberg addressed white privilege (and how it's often "invisible" to white people) through Carson's realizations as he travels with Aisha. But... there is a LOT going on, and maybe this is my bias as an adult reader, but I get a bit perturbed at YA where the teens are infinitely more self-aware and wise than most of the adults in their lives. Plus, there's a bit too much of the John Green-esque implausible teen banter.
So, as I'm a bit on the fence as always, I will happily defer to the crowd and vote for The War That Saved My Life. No smacking this time, sorry! My zombie pick goes to Wolf by Wolf.
