My daughter Jenn recommended that I read this novel, which tells the story of a black couple in the South whose marriage gets torn apart by a horrible incident of injustice. Jones is such a good writer that she manages to make you empathize with both of her main characters, even after one makes a difficult decision. The subject matter is heavy but thought-provoking, and I got sucked into Roy and Celestial’s tragic love story.

Lepore has pulled off the seemingly impossible in her latest book: covering the entire history of the United States in just 800 pages. She’s made a deliberate choice to make diverse points of view central to the narrative, and the result is the most honest and unflinching account of the American story I’ve ever read. Even if you’ve read a lot about U.S. history, I’m confident you will learn something new from These Truths.

When I first heard that one of my favorite authors was working on a new book about growth, I couldn’t wait to get my hands on it. (Two years ago, I wrote that I wait for new Smil books the way some people wait for the next Star Wars movie. I stand by that statement.) His latest doesn’t disappoint. As always, I don’t agree with everything Smil says, but he remains one of the best thinkers out there at documenting the past and seeing the big picture.

As any parent knows, preparing your kids for life after high school is a long and sometimes difficult journey. Tavenner—who created a network of some of the best performing schools in the nation—has put together a helpful guidebook about how to make that process as smooth and fruitful as possible. Along the way, she shares what she’s learned about teaching kids not just what they need to get into college, but how to live a good life.

I read a couple of great books this year about human behavior, and this was one of the most interesting and profound. Both Jenn and John Doerr urged me to read it, and I’m glad I did. Everyone knows that a good night’s sleep is important—but what exactly counts as a good night’s sleep? And how do you make one happen? Walker has persuaded me to change my bedtime habits to up my chances. If your New Year’s resolution is to be healthier in 2020, his advice is a good place to start.
