This book is a must for any person living or visting Chicago in search of Ghosts or the paranormal. The author is a real-life ghost researcher for the group that was featured on Discovery Channel's "Real Ghosthunters." The book explains what is going at a specific location, gives you directions on how to get there, and even includes a map. This book is a dream come true for any paranormal investigator! Anyone looking for Bachelors Grove Cemetery or Resurrection Mary? Monk's castle? Then you need to pick this up and read the book. It's a great book that I am glad to have purchased. Many locations that are hard to locate are made easy with this book. Excellent!!
