Ten-year-old twins Ashlynne and Julian share a special ability: the power to enter each other’s dreams. They call it ‘sharing’ dreams. It’s usually a great time; playing together in a dream is way more fun than playing in the boring real world . . . until one night, when the twins find themselves stuck inside a dream that feels all too real. The pair must work together to find a way to wake up—and they need to hurry—because the dream is quickly turning into a nightmare, thanks to an ancient evil bent on ensuring they never escape . . .
