Stunning Review
Format: Paperback
I thought the book was a great book. The book is about a man who is a journey to Santiago. But on his journey he encounters a lot of paths that he needs to over come. He has to dig deep down and find the true him and over come many things. The purpose of this trip is so he can become a new person and do many new things that he has not done before. This will bring out a new him and this will help him as he goes on in life after this journey. The thing in the book that got me noteworthy was how he had the drive and how focused he was to make it to the end of his task. The strength of the book was it was very detailed and this was a very good thing. The weakness of the book to me was I thought the ending was just a little dry, I felt as tho they could have added just a little more to it. I like the authors writing style this was very good on how he wrote it. It was well written the words all followed very well and his was a great thing. I think the message of the book is to show you that no matter how hard things may get never give up. There is always a road of something to come at the end of everything. I would recommend this book to anyone who likes a book about a journey or a path in someones life. I think it is good to read as a class because you really get to see what others think of the book together. I also think if you like a book about a person that is going thro something in life that this is a good book. The book just expresses so many trails and then he some how over comes everything. So if you like to read go head and buy the book.

I very much enjoyed the book
Format: Paperback
Malcolm A. Ivy The book " The Pilgrimage" written by Paulo Chelho, is a story about one man on a quest to find his sword. During his journey he encounters multiple aids , hazards, and traitorous tribulations, that has him question not only his phish all capabilities, but his mental capabilities as well.Accompanying him on this journey is his guide Petrus, who leads him down the road to Santiago. Teaching him many different ram practices along the road. Throughout the book we see Paulo's overall character develop ,and mature through many vigorous challenges. I very much enjoyed the book, for both content and overall story arch.I enjoyed the progression of all the characters, and looking into their minds, and experiencing their inner most thoughts. The story is extremely detailed, and vivid. This book always kept me on edge to see wether Paulo does in fact get his sword, or not. The book however did ramble at times, but in a nutshell it was rather intertwining for a book about two guys walking. I liked this book for the underlying message stating that the most hardest questions, often have the simplest answers. I highly recommend this book if you want to kill some time. This book has a lot to offer, and will leave you questioning your self, and your own thought process. You would never want to put this book down because it keeps you in a stage of Suspense. Mostly , because it's a book you can take, and learn from. So if you are looking for a book that makes you reflect, this is the book for you.
