The first book is Dreamland by Sam Quinones.
Dreamland is the best book out there about America's opioid addiction epidemic, a national health crisis that has become our generation's AIDS.
Seriously, if you're a church and you're not tracking with the opioid epidemic you're massively out of touch with what's happening in your city.
This is the best book about poverty in America that I've ever read. Many people have pointed to Hillbilly Elegy as the best recent book about Rust Belt America, but I think Evicted is way, way the better read. Evicted is focused on both whites and blacks and gets you more into the nuts and bolts of how the system affects poor people, their housing especially.
If your church is interested in poverty, housing and homelessness then you need to read Evicted.
