Something was wrong. The window was open. I had never opened it. Aunt Puff hadn't either. Had Minerva? I looked back at her seat. Minerva's leopard-print cowboy hat lay on the floor. "Minerva!" Ludwig growled, sniffing the air. Ciber squawked furiously, banging his feathers against his cage. Smoke swirled round the chair where Minerva had been sitting. The silly hands tried to fan it away. I gulped. Ludwig covered his eyes with his paws. Minerva had vanished." Aunt Puff's old friend from the Elcarim Foundation has come for a summer visit. But, before you can say "Marbles!", Minerva has disappeared during a game of bubble gum charades. Aunt Puff, her niece Alexandra, her Great Dane Ludwig, and Minerva's cockatoo Ciber jump out of windows, battle flying fish, run from lemonade, splatter fudge on ghosts, and even fly with pinwheel power in their search for Minerva. But is someone more sinister than a muumuu wearing Siren behind Minerva's disappearance? It seems Orpheus's harp has been found. And, dragons are afoot.
