An interesting book that could help change leaders achieve their goals. I tend not to like using language like "superhero" in business, but I understand the snappy attractiveness of the term to grab people's attention.

Carney offers some interesting advice, suggestions, and prescriptions to help those understand change: why it happens, how to do it, how to sustain it, and what is the human side of it. (Something that is all-too-often forgotten in books about change.)

Most books about organizational change, in some way, reference or build on Kotter. So, if you're interested in the subject, I would also recommend you pick up his work on the subject. (It offers a great grounding that will enrich most reading you do afterwards.)
