I read this book during the Covid 19 pandemic and while it has a lot of science fiction elements in it, the political and cultural and religious elements are eerily close to what we see playing out right now. In this book, the main character's younger sister is the first of the "walkers", a growing group of people who are strangely sleepwalking across the country. The CDC joins the group trying to determine the cause of the strange phenomenon, but some of the CDC members are later called away to deal with a pandemic which some people believe is caused by the walkers. As the pandemic progresses, we see conspiracy theories, right wing militia groups, religious zealots and mass anarchy. It is a kind of creepy book to read during a pandemic.
