Query: The Best Book Yet for Anyone Undergoing Change

As someone who's helped plan and implement major change initiatives at numerous companies (and numerous corporate cultures) I've had a large stake in searching for and hoping that someday someone would publish a helpful guide focusing on the human aspect of change, the emotional roller coaster ride experienced by the employees undergoing the change--rather than the often dry treatises focusing on structural archetypes or the academically-oriented anthropologist's view of change. Jeanie Duck has done, and done it beautifully. If you are undergoing change at your workplace I can't recommend this book more strongly. I've already given it to several people I've worked with who have come back to tell me how helpful and meaningful they found it.
