In my book club, we read The Molecule of More, which is all about dopamine. I didn't expect to be so fascinated by the topic, but there's a lot to learn about dopamine. As with all pop psych books, I went in with some apprehension and skepticism, but I'm happy I read this book and would suggest it to anyone looking for a deeper understanding of our chemical relationship with longing, desire, apprehension, and unease—feelings that all of us experience as humans.
