In 2007 Paul Gordon published The Unplanned Card Book which contains unusual (but strong) semi-advanced impromptu card effects. It became an instant success and sold out within a year. Well, it's back. Back as a kindle pdf. 175 pages of goodies. Not for beginners but not advanced, either! Paul Gordon is a professional card magician, creator, lecturer and author. His magic has received plaudits from the likes of Roy Walton, Harry Lorayne, Jon Racherbaumer, Aldo Colombini, Boris Wild, Alex Elmsley and many more top cardmen.
