There's something special about a book like this — obviously there's a plot, but the story is driven by characters you can't help but root for because they're so vividly human. None of the twists were really unexpected, but I think it really worked: I didn't want to believe it about Felix, but I never gave up on him completely either. The way it worked out just seems the most reasonable explanation, consistent with the characters I spent the book getting to know, as a happy bonus to it being the most acceptable series of events. Obviously it doesn't bring Vanse back, but I'm glad Felix and Jottie finally found closure and a healthier way to coexist. And as for the others, Willa and Layla and Emmett and Bird, I'm really glad they got their happy ending.
