I've been dipping in and out of this book between swimming sessions. It's nicely formatted into separate, detailed sections for each stroke with clear, good quality photos. Some of the advice is a little unconventional, as it's emphasis is on using the Alexander Technique whilst swimming so as not to strain the neck and joints. Some of these tweaks and changes have definitely helped me to improve my stroke (especially front crawl, as that was always my weak spot). Others I'm struggling to incorporate into my swimming routine - old habits die hard. I don't think this is book is for the experienced/sports swimmer - it definitely emphasises Alexander Technique over sports/speed techniques. But, if like me, you like to swim as part of your exercise routine, and you'd like to improve your stroke and become more confident in the water, then I would definitely recommend this book.
