The Doom of the Haunted Opera, by Brad Strickland, John Bellairs, Edward Gorey

4.0

When Uncle Jonathan and Mrs. Zimmerman leave town for an old friend's funeral, Lewis and Rose Rita think they'll have a quiet couple of weeks researching a school project on the local defunct opera house. They're wrong, of course, because the opera house is haunted, of course.
We love this series for its great characters and its spooky-but-not-too-scary atmosphere. Perfect for kiddos who like supernatural sorts of stories but don't actually like to be scared.
