Q: excellent reference . Like other reviewers, I agree that a book is no substitute for instruction by a teacher. Nevertheless, this comes as close (for the Yang style short form) as anything I've found. Even if you have no interest in the martial aspects of taiji, having the potential applications of the form enriches practice. I found the illustrations clear. I own a half dozen or so books on taiji, and this is the only one I regularly consult

Q: One of Walters' Best . THE SCOLD'S BRIDLE, in my opinion, is one of Minette Walters' best mysteries--at least one of her best I've read so far! Her characters are well-developed, and the reader doesn't know from one page to the next who the murderer could be--NO ONE liked Mathilda, it seemed. Throughout the police investigation, readers are faced with learning of Mathilda Gillispie's abusive and haunting background of secrets, lies, and deception. Mathilda's character, though dead as the story begins, is developed more fully through her diary entries interspersed between chapters. Having left all of her money to an unlikely person, her doctor Susan Blakeney, Mathilda's daughter and granddaughter are brought into the story assuming they would inherit Mathilda's wealth. Readers find that Mathilda's daughter and granddaughter have experienced much of the intense emotional and physical abuse as Mathilda had. This part of the story, no doubt, leaves readers pondering how abuse often perpetuates itself through generations. Walters doesn't let on who the murderer is, and I'll admit, I was a little disappointed in its resolution given that the novel seemed more focused in a different direction. Overall, I enjoyed this novel moreso than THE ICE HOUSE or THE SCULPTRESS, but they are all very good books, and I would wholeheartedly recommend Walters to readers wanting a good mystery

Q: Warning this book is intended to make martyrs . Guerrilla Warfare: Che Guevara by Ernesto Guevara Warning this book seems intended to make martyrs Over the years this book has proved far more useful to mislead potential guerrillas than to educate them. The handmade weaponry described are ineffective and or failed tools of war. The tactics suggested have led to defeat in the Americas and in Africa. The cause described has never helped the poor and down trodden. One could readily ponder if the real intent was to make martyrs for the cause of mythical communist paradise. One wonders how many, aside from the author, died violently because of all the above.
