Query: I couldn't put this book down!

This is the first book I read by Katherine Ramsland and I must say I couldn't put it down. I was fascinated by the story of the haunted ring and I stayed up all night reading this book. I'm not easily frightened but this book gave me a good scare and for a few nights I was afraid to turn the lights off to go to sleep! I really enjoyed following along as Katherine learned to be a certified ghost hunter and I very much enjoyed hearing about her travels to haunted places around the U.S. If you love a good ghost story and all things paranormal then you'll love this book!
