Anne Lobeck, Kristin Denham. Navigating English Grammar: A Guide to Analyzing Real Language. Malden, Wiley-Blackwell, 2013.

An engaging and fresh take on the rules and politics of English grammar, written in lively prose. It goes a step further than most books on grammar by providing an overview of the field, with a discussion of historical and current debates about grammar, and how we define, discuss, and approach it.
