Q: I have to say this: I enjoyed this book from top to bottom. Terry is there all right, with its excelent writing and a very, very odd way of looking at things. Of course, you laugh your eyes out in almost every page, specially with the screams of the shelled God Om and the comentaries of Dydactilus and Urn. And the book has one of the best endings I have read in a very long time. Lets just said:I. Is Godly.II. Respect tortoises over yourself.P.S. If I had the incredible memory of Brutha, surely I would be a prophet, without the requisite of crossing the desert, although maybe not having that much fun.
