Liza G. Walsh's latest book is all about finding ghosts. It's called "Ghost Hunter's Handbook: Supernatural Explorations for Kids."
She looks at the history of ghosts, how to find them and - something you should definitely be prepared for should you find success - what to say to them.
The book was born out of a previous research effort that took her to Fort Knox in Prospect, which piqued a lot of interest in the subject of hauntings.
Liza says she maintains a healthy skepticism about ghosts, but does have an experience she can't explain.
