Judy Moody and the missing mood ring

"Judy Moody is freaky for Nancy Drew, the famous girl detective from the book series . . . So when Judy bumps into Mighty Fantaskey, she is excited to meet another Nancy Drew fan and to make a new friend. Excited, that is, until she visits Mighty's house: it's big and old and creaky and definitely haunted. It even turns Judy's mood ring the color of fear! On Judy's first visit, she hightails it out of there, leaving Mighty in the dust. But where is Judy's favorite ring? Jeepers! Can Judy pluck up enough courage to go back and find it--and solve the real-life mystery waiting in Mighty's attic?"--Provided by publisher.
