Adding an extra star to emphasize that I am not a big fan of thrillers, and in the end that’s the genre this book fits into best. It’s not so much that there are twists. Most thrillers are more interested in making you guess what happened, but this one wants to make you guess what matters - to the author as much as the characters. The book doesn’t aim to trick you the way most thrillers do. It’s exploring a very particular idea and it follows the thread of it through multiple POVs, revealing the past slowly until everything starts to fit together and clarify what it’s actually interested in. All the assumptions I made at the beginning of the book weren’t wrong so much as unimportant. Where the book starts reveals very little about where it ends. I appreciate that control of structure. And I have to give extra points for the inclusion of the Arrowood stories. They add a layer that without being frustrating, and sometimes provide a welcome break from the other POV sections. It’s also fun to see a writer who clearly knows her craft intentionally write badly.
