If you have kids who are interested in steamboats (or just want a fun, fast read for yourself), check out this book:
Haunted Book 2: The Riverboat Phantom
Jon and Tania are back and tracking down more ghosts, this time on the Mississippi River on an antique riverboat. With them are their mother and stepfather, producers of a hit TV show about "real-life" ghosts -- a topic no one on the crew seems to take all that seriously. But Tania has a gift -- she can see and communicate with ghosts, and this time she's in touch with the spirit of a riverboat captain who accidentally caused the boat to catch fire, and he's making trouble for everyone. Will Tania be able to help this troubled spirit find peace before disaster strikes again?
In the Haunted series, for ages 8-12, a brother and sister travel with their parents’ ghost hunter TV show. In each book, the TV show researches a new ghost at a new location. Read the first chapters for free Haunted - Chris Eboch.
