This is a fabulous excursion into a world inhabited by all sorts of mythical creatures: Calabi-Yau 3-folds, D-branes, orbifolds, ten and eleven-dimensional backgrounds, supersymmetric partners, covariant fermionic vertex operators and many others that only the wildest imaginations can conceive of. The wizards and magicians who have conjured these beasts have also cast a powerful spell on their easily-beguiled followers who see streets of gold and emerald trees as they walk through the morass of E8*E8 gauge fields, compactifications and dualities. This tome will be a welcome addition to your bookshelf right between Harry Potter and Alice in Wonderland. I gladly recommend each of you to take a brief stroll into this enchanted land to be followed by the volumes of Landau and Lifchitz, so that you will be able to find your way back to reality again. Some have called strings "a theory of anything". Indeed, it is a wonderful place where you can make all your wishes come true. But do not stay too long in the kingdom of string theory lest you end up like so many others who are lost, searching endlessly for the legendary realms of M-theory or wandering aimlessly in the infinite labyrinth of the Landscape, wasting the remaining years of their life on naught but a fable.
