The dreaming stone
(Book)

"It was just a small stone in the shape of an egg and a common-looking set of panpipes, but when Stacey put the stone under her pillow and Alex played on the pipes, they were magically transported back into the world of Greek mythology. Join Alex and Stacey as they ride on the back of the winged horse, Pegasus, descend with Orpheus into the dark depths of Hades, fly with the ill-fated Phaethon in the Golden Chariot of the Sun, help Perseus slay the evil Medusa, and face, alongside King Theseus, the dreaded Minotaur."--Page [4] of cover.
