You’re almost certainly familiar with Kahneman’s and Fredrickson’s wonderful ice-water experiment (“When More Pain is Preferred to Less”, also called the peak-end rule), the one where victisubjects opted for a longer (90s vs 60s) painful experience if the last few seconds were less painful. I love that result. I’ve found it invaluable for reframing life situations.

This is a 436-page book, of which the first 220 or so pages are excruciating. Oh, how I wanted to toss it away! But I was encouraged to stick with it. I did. And I’m glad.

Halfway through, it took an interesting twist, and yes it was foreshadowed but no, not the directions it took after the midpoint. That was thoughtful, creative, nuanced, suspenseful, engaging, and even sweet; and it just kept getting better. A whole lot of Did Not See That Coming, even when you think you see what’s coming, and damn, I really loved it. Solid 4.5 stars, but rounding down because even with all that praise it was still objectively heavyhanded (I know, it’s YA, I should be more forgiving); because of the eyeroll-worthy dei ex machina and other wildly convenient coincidences; and finally because I can’t objectively be sure if the last half was truly-actually good or if I was swayed by the peak-end rule. What I can say is, I’m really glad to have read this and can highly, highly recommend it but only to those who promise to persevere through the first half. Tesh took a big risk in writing the book that way, and I’m sure it cost her sales and readers. If she decides to go for the adult reader market, I’m looking forward to seeing her future work.
