Off Centered Book . Love the beer but found the book to be more a rambling stream of consciousness that doesn't really have a point.  It really seems to be just Sam's rambling thoughts and recollections of his startup.  There are some great anecdotes woven through the book (and I'm sure he has plenty that aren't shared).  He goes over some of the many questions that any startup should answer but the business advice in the book is fairly basic.    At the end of the day I'm not sure what the point of the book really was supposed to be as several subjects are visited repeatedly.  It dosen't go into the brewing in any depth and there's certainly not enough substance to call it a business book.  If your a really huge fan of the beer you may have some interest

Ex Output:
NEG

Another not very exciting Lt. Bak story... . I keep trying but cannot get interested in the stories by this author.  They seem to drag out with her style of "he said/she said" writing with nothing exciting, except perhaps one part in this book.  The story begins as the famous Lt. Bak is asked by his commander Thuty to investigate the disappearance of an explorer named Minnakht. His guide, Senna tells Bak of the disappearance and attraction to turquoise mines near the sea.  The land is hostile and murder and death come as Lt. Bak questions each man over and over. The ending was not exciting or unexpected. Lt. Bak's constant referrals to the donkeys (we know how he is sympathetic to animals, this big strong medjay!! I had to make myself sit and finish it.
