"So You've Been Publicly Shamed", by Jon Ronson, and "The Invaders: How Humans and Their Dogs Drove Neanderthals to Extinction", by Pat Shipman, are my two best reads this year (that were published in 2015). The first is a great analysis of the phenomenon (usually Twitter-based) of shame-storms, and the second is about the far, far older phenomenon of one invasive species driving a closely related one to extinction. Both very well done.
