This book was such a pleasant surprise, adding more layers and thought-provoking plot twists with every page turn (and the short, cliff-hangery chapters and unreliable narrator didn't hurt either). Completely fascinating, and had me thinking a lot about the development of ideas, the "ideal world," and what makes a good life. I have a bunch of highlights in my Cloud Library copy that I will have to see if I can access. 
 Update: I found out that highlights are not preserved on my Cloud Library account, so I sadly do not have my favorite quotes from reading. Here are a few I found on Goodreads that I remember: 
 "There's no such thing as the life you're supposed to have." 
 "People talk about grief as emptiness, but it's not empty. It's full. Heavy. Not an absence to fill. A weight to pull. Your skin caught on hooks chained to rough boulders made of all the futures you thought you'd have." 
 "Every person you meet introduces the accident of that person to you. What can go right and what can go wrong. There is no intimacy without consequence."
