This seems to be one of the classic texts on user stories. It is generally quite well-written and organized with copious examples and a several-chapter case study at the end. It gives a clear understanding of user stories, what they're for, what they're not, how to write them, how to prioritize them, and how to organize them into iteration planning and final testing.
The book has a couple downsides. First, my copy cost 41 Euros, which is at least twice as much as it should have. It's a print-on-demand book from 2004 with around 250 pages - the cost is extortionate. Second, it's somewhat dated. It assumes the reader will be coming out of a waterfall development mindset and does a lot of explanation of Agile and arguments on its behalf. It also seems to have been written before product management orgs reached their current status as a major component of most software companies, so the function is rarely mentioned and not much considered. And some of the terminology is a bit dated - what we would call jobs-to-be-done these days is called Goal Stories, for example. Third, stylistically, the writing is at times a bit odd. I have several examples, but the one I'll mention is that what most people would call "red flags," Cohn calls "smells," which I found a bit weird.
Modern readers might blanche at the price, need to skim the stuff on why scrums are good, and translate references to customer teams into product manager equivalents, but at the end of the day, you get what you came for - a solid, comprehensive overview of the topic.
