Of course, I thought I'd be different and actually enjoy this book since I really enjoyed the movie. But, no. What a train wreck! The first half was great; I'd give it 4.5 stars. A post-apocalyptic wandering bard finds a postman's outfit and begins delivering the mail, hope, and unity to the scattered masses. Lovely. It could have cleanly ended there and all would have been well.
The second half of the book is, at best, 1.5 stars. It's as if someone else wrote it, and it barely resembles the first half of the book at all with its "three myths". These myths (that would have been better left out) are an obvious wizard of Oz, a foolish band of feminist warriors (who infiltrate the enemy's beds), and augmented super soldiers (one of which is a hippy martial arts new age "dude"). The author also throws in some drug-laced tobacco into the mix (which I'm pretty sure contributed to the author's insane writing of the second half of the book).
Save yourself the trouble before reading; rip out the last half of the book and burn it. Don't put yourself through the misery. Really. And if you don't, don't say I didn't warn you.
