Interesting history of a variety of English words, especially the final section about common confusions that would be great for people learning the language.
There was a large section through the middle of the book that focused on new words such as "ghosting" and "YOLO", and as someone who has kept up to date with modern trends, these parts were written as if they were speaking to people who've been living under a rock.
Good for the home library but feels more like a collection of digital articles in book form.
