The thing about Casey McQuiston is that they can write basically any trope and even if I don't usually love it, I will absolutely buy it.
I'm not a huge second-chance romance person except apparently when I am. This was incredibly well done, in part because McQuiston let the characters grow on their own before bringing them back together and in part because the setting is one of those "of course anything can happen" settings. There's also this very "contemporary trends in romance" aspect to it, where love is not the things that offers you fulfillment, but love is—in some ways—the reward for finding yourself.

By being able to live without it, you earn it

and I'm totally on board with that and also fascinated by it in my larger "romance novels are extremely nuanced guides to a culture's values" theory.

Also I strongly recommend reading this book in the summer when there are foods that taste good available because the only part of this book when I wasn't salivating over the food and drinks was when I had a mild case of food poisoning.
