The only memory-book I've read is "How to develop af Super Power Memory" by Harry Lorayne and it is really worth the money! You'll learn how to remember 52 cards in order, and so many other things.
Harry Lorayne writing is entertaining and his techiques are very easy to grasp. He doesn't tell much about how the brain excactly remember things and where it takes place in the brain and all that, but I think that's also what makes it such an easy read. Go buy it..
