Christina's Ghost — Betty Ren Wright

"You mean he's a ghost?"

The last thing Christina wants to do this summer is stay with grumpy Uncle Ralph in his old Victorian house. She's sure she'll have an awful time. But on her very first day there, Christina meets a sad, mysterious little ghost boy who seems to need her help.

Soon Christina discovers the house contains a mystery that was never solved...and that the ghost boy has something to do with it all. But how can she make Uncle Ralph help her solve the puzzle? What is the evil, chilling presence that lurks in the attic? And why is it trying so hard to frighten her away?
