Listened to this on audiobook, which it was pretty good for. I wasn't expecting much and therefore it met my expectations. I liked the structure of weaving together all the different storylines, it was decently well written. After a while I started getting annoyed at how useless everyone was after their tech stopped functioning, it's not like ALL knowledge disappears and suddenly people are like "huh, wow, I simply cannot fathom HOW airplanes worked?" idk.
