A fairly good book that expands the Business Model Generation book with more analysis and some small new models. But the new models are not what is really important, but the help it gives to summarize the practitioners thinking. The bad side of the book is that it has very shallow case studies and is not very intuitive, but if you read it with some concentration, these drawbacks can be mitigated.

In short, a good read that is dependent on having a good knowledge of the previous books.
