There's a Dead Person Following My Sister Around

When Ted's five-year-old sister Vicki invents an imaginary friend, no one is too concerned...until they realize that her friend can move things. Ted is sure that Vicki's "friend" Marella is a ghost. But why would a ghost haunt Vicki? And why does Marella seem to be terrified of another ghost-a dark figure that is haunting Ted? Edgar Award-winner Vivian Vande Velde's blend of history, humor, and suspense is sure to keep middle readers turning the pages!
"A fast-paced story that mixes scares and history for some can't-put-it-down fun."
