The Ghost of Sullivan Town

When Niki and Hugo went to work in the library for the summer, they hadn't counted on the ghost in the basement. A ghost who hadn't yet learned how to materialize properly. A ghost with a sense of humor. And a ghost who decided Niki and Hugo were going to help her find out who had given her the fatal push down the basement stairs.

Niki and Hugo get caught up in the mystery -- and you will too, as you meet the fascinating people who lived in Sullivan Town.
