The Essential Cruise Book by Jim West is a great book. It isn't very big, and it's an easy read. Jim is or was a cruise director, and he relays a lot of great information on many, many subjects. Even though I had cruised before I found some of the information very useful.
One of my favorite chapters is the one on packing. He says, "Do not overpack." Follow his advice!
