Joyrides

Riz, Anvita, Tiana and Palash, the Fearless Four, have just finished a terrifying case involving demonic toys and feel they have earned a holiday. They head for Funmania, the big amusement park on Bongo Island, where the world's biggest rollercoaster, Big Loopy, is waiting. The island feels wrong almost from the moment they land. At night the eerie wails of the Wailing Witch carry through the dark, and the locals watch the visitors from the shadows, as if guarding secrets the friends cannot yet guess at. Then their friend Cyrus disappears. He was strapped into a seat on Big Loopy one moment, and the next the seat was empty, with no trace and no explanation. Now the four must uncover the island's chilling mysteries before Cyrus is gone for good, and before they become the next to vanish.
