10 best books of April, according to Amazon's editors

What are the best titles to check out this month? Here are Amazon's picks.

2. 'Gulp,' by Mary Roach


The book by Roach, who has also written nonfiction, science-oriented works such as "Packing for Mars," focuses on the digestive system and how it functions – not a topic you would expect to be described as humorous, but Nelson says she was completely won over. "She's so quirky and weird as a writer," she said of Roach. "She's writing about pretty basic bodily functions and she's hilarious."
