Upon seeing this book you might think "we can't possibly need another book on the Sword Coast", and while that might be true my friend, that is not what this book is about! Coasts of the Realms focuses, literally, on the coasts: the beaches, the waves, the surf, the shallows, etc. And aside from a brief humourous tale of the newfound popularity of swimming for pleasure among Waterdeep's elites (and my, what swimsuits!), most of the locales detailed are far away from the venerable adventuring region, giving us wonderful updates on other areas of the Realms and what is going on there in the 1490s DR. Another smash work in this incredibly well produced series!
