I buy this book has its output and seeing the comments, I'll add mine. For those who have managed to finish the I congratulate !! But I, great fan of Werber, I have NEVER been able to finish that book. . . Why? Once immersed in it, and my imaginary party in this other world, and although my body falls asleep peacefully in the middle of the book, for a night, wonderfully relaxed ... it's worth every Xanax, all Temesta while the Valium of the world !!!!
