This book describes Unity's animation techniques from a designer's point of view. It is focused on achieving interesting gameplay effects and creating game mechanics. Each topic is presented in the form of a short recipe with a list of steps needed to implement the given feature. All the recipes are prepared in the most condensed form—a good basis to build your own solutions on.
This book doesn't cover animating in a 3D package, although you may find some helpful tips regarding Blender 3D in it. A lot of the recipes presented in this book use C# scripting not only for triggering animations, but also for creating interesting motions and effects. If you are a game designer or a Unity developer and would like to know more about what's possible with Unity's animation system, I hope this book will be an interesting read for you. Also, if you have any questions regarding this book or the topics it covers, you can contact me via Twitter (@MaciejSzczesnik). I will be happy to help.
