The brother-sister pairs who arrive for the summer at Camp Happy Harmony are almost too busy fighting with each other to notice how strange the camp really is. Not only are the campers forced to wear bizarre uniforms, eat gross food, and do chores all day, but the members of the family that runs the camp fight constantly - with each other. Are the campers in danger? Or - in spite of sibling wars - do they need to stick together to solve the mystery humming under the surface of Camp Happy Harmony? Ages 8 to 12.
