What happens when Geo's fortune-telling scheme exposes what seem to be some very real manifesting abilities?

Thirteen-year-old Geo Leoni desperately needs to earn some cash this summer, fast. So she launches a fortune-telling business using her best friend Lana’s rock collection for props. Does it matter that Geo doesn’t believe in psychic powers? Or that she knows nothing about rocks and crystals? Nope! She’s happy to tell phony fortunes for anyone willing to pay.

Geo’s scheme is quickly a hit, which should be great news. But things take a turn for the weird when her fake predictions start coming true. Like, all of them. Her friends are convinced she’s a psychic for real, and Geo desperately wants to prove them wrong. Because logical people don’t believe in psychic abilities, healing energies, or whatever the heck manifesting is. . . . Do they?
