Tilted World by Tom Franklin & Beth Ann Fennelly
The authors have created memorable characters in Ted Ingersoll and Ham Johnson, two revenuers working for Hoover to catch bootleggers along the Mississippi during prohibition in 1927. Dixie Clay, a young newlywed becomes a bootlegger for her philandering husband and has a reputation for making the best whiskey in the region. Along comes an orphan who needs a home and record rainfall that won't stop. Levees are undermined and priorities change. Very good, I recommend this book!
