Dial-a-Ghost by Eva Ibbotson

Can you believe that some people would love to have ghosts in their homes? What happens to ghosts if their homes are destroyed and what is built doesn't suit them? Dial-a-Ghost is a match-making agency that places homeless ghosts with new families. Sounds easy and simple, but could a mix-up that leads to a comedy of errors really save a young boy's life? Why would a loving uncle really want to scare his nephew to death? How can a family of kind ghosts keep that from happening if they're limited by being ghosts? Where did those scary ghosts go and how does that involve a group of nuns? Please don't read this if you have strange noises that go bump in the night or branches that hit your window. The last thing a need is another parent complaining that I give their kids nightmares when I just tell a few stories or suggest a great book.
