Ashes, by Ilsa Blick

Unrelentingly dark YA. 17 year old Alex is on a solo hike when EMP bombs are set off. Horrifying scenes ensue, and that's just in the wild- when she meets humans, that's when the real trouble starts. Really disturbing images and some pretty ghastly violence made this a hard read, but I struggled through it hoping for some kind of redemption or hope- yeah, not so much. This read more adult to me, just for the level of horror and the utter hopelessness.
