Nudge
Nudge was one of April's Jack Covert Selects, but it appears Jack and the rest of us here at 8cr are not the only fans. Mr. Tom Peters himself has posted a rave review on his blog.

At any rate, the book is well worth a careful read. At one level its principal thesis is obvious (except, as the authors point out, for economists who are obsessed with the mythical "rational man," of which there is none on earth), but the power of the ceaseless examples is likely, I think and hope, to grab your attention.
