Steve Gubser has released a new book on string theory. Unlike Joe Polchinski's book, which was referred to as Joe's Big Book of String, Gubser's book is the Little Book on String Theory. ;-)
At the beginning, there are three paragraphs that start with "String theory is a mystery."
You may feel that the author had to be either poet or a computer program stuck in an infinite loop. But without using any mathematical equations, the author begins with the notion of energy and quickly gets to quantum mechanics, gravity and black holes, string theory, branes, string duality, supersymmetry at the LHC, and heavy ions and the fifth dimension.
Yes, I just gave you the table of contents. ;-) Introduction, epilogue, and index are parts of the package, too.
