With regard to the specific topic of communicating through a crisis, I've found Masters of Disaster: The Ten Commandments of Damage Control by Christopher Lehane, Mark Fabiani and Bill Guttentag to be pretty interesting. The authors worked with multiple organizations and celebrities during time of crises and helped them with the public relation side of it. For instance they managed Bill Clinton's PR during the Monica Lewinsky events. The book is not perfect (I think it could be shortened a bit and retain the same information) but it is still very interesting and I think about it every time I witness someone getting themselves into a big, public crisis and making things worse by not managing their PR properly.
