All the Missing Girls
This book is a mess. It’s got a kind of interesting sort-of mystery at the heart of it, told in a way too-clever manner of going backwards in time from an arbitrary point that is both hard to follow and completely incoherent once it all resolves—as you’d expect, the resolution of the mystery is near the end of the book, which puts it near the start of the timeline; so how did she spend the rest of the book not knowing? The resolution is also silly. What she treats as inevitable is anything but.
