Coulrophobia—the fear of clowns. It might seem funny, but for Josh this fear is no joke. Josh has a pulse-pounding, sweat-inducing feeling about the clown that advertises the local pizza place. Or anyone who dresses up as a clown for Halloween. When a class field trip takes him to an amusement park, Josh's friends dare him to enter the Hall of Horrors. Will one of those horrors be wearing a frizzy wig and a red nose? Josh is on his guard, but then someone else gets into trouble and needs help. Can Josh muster the courage to conquer his greatest fear and come to the rescue?
