Digital or Death is the first book on the world of digital strategy that won't bore you to sleep. It takes an entertaining, highly informative real world approach with enough information and energy to get you inspired to innovate. Dominic Mazzone is part digital guru, part comedian, part entrepreneurial titan. He has the uncanny ability to get you thinking in a way you never have before, while creating the motivation you'll need to succeed. If there was a book that could actually increase your drive and expand the creative part of your brain, this is the one.
If you want an entertaining read on some aspects of digital transformation, this is it. However, it is not very actionable. Information on the innovation, change and adaption of the digital transformation is superficial and really limited to "get experts to do it". The digital transformation examples are similarly very plain and basic. This is ok because that makes them very realistic. Hence, if you need basic information on digital transformation, and inspiration about what is required to have a foundational "digital transformation mindset", this is an excellent start. Likewise if you already has a base within digitalization, there is little of interest. If you want something that really gives you a hint about what revolution the digital transformation is capable of, I would suggest reading "Automate This: How Algorithms Came to Rule Our World".
Finally, If you like a more critical perspective on digital transformation - this is absolutely NOT it.
