For unexpectedly awesome, Suarez's Daemon and Freedom.

SPIN is still great.

The best books, hands down, are Neal Rackham's SPIN Selling series:

For actual book as book, probably "First In; How Seven CIA Officers Opened the War on Terror in Afghanistan" by Gary Schroen. They basically went in with $30mm or so and an old helicopter, 2 SF ODAs, and accomplished most of the good accomplished to date in Afghanistan within 2 months.

For unexpectedly awesome, Suarez's Daemon and Freedom.

SSI Open Water Diver. Not because the book is particularly (or at all) well written, but because it was my entry into an amazing hobby -- SCUBA diving.
