Much like Under the Tuscan Sun or You Me Everything, People We Meet On Holiday by Emily Henry is about finding the unexpected with someone you already know like the back of your hand. Poppy and Alex are complete opposites, and have been best friends for a decade. But two years ago, something occurred that made them stop speaking, and almost lose that friendship forever. Now, they've decided to embark on one final holiday together and fix it all: but there's a secret that may risk everything.
