Scared Stiff

Once again Roberts ( The Magic Book ; Nightmare ) has written an enticing, suspenseful mystery for young readers.

While she is missing, the boys stay with their uncle, who lives in a trailer adjacent to the deserted Wonderland Amusement Park. The brothers explore the park with adventurous Julie and Connie, who befriend them. Since the police are unwilling to investigate, Connie convinces Rick that they must track down Ma themselves. The plot's exciting climax takes place in Wonderland's slippery, winding Pirate's Cave. The clever sleuthing and intriguing setting will make readers want to ride this one to the finish. Ages 8-12.
