Twin witch sisters Bella and Donna peek into the future in this fourth book in the middle grade series that's Wizards of Waverly Place meets Halloweentown.
There's a psychic visiting at YIKESSS, and twin witches Bella and Dee are fascinated to hear her speak at a school assembly. True clairvoyance is a rare trait, even in the supernatural community, and they've never met one before—and likely won't ever again.

Except the son of the new owners of Scary Good Shakes seems to be eerily good at diverting disasters before they happen, like when he catches a tray right before it falls or when he stopped Charlie from eating garlic, which, as a vampire, they're highly allergic too. When Bella and Dee start to notice more evidence that supports Henry being clairvoyant, they realize another psychic might be in their midst. And he's human. And he has no idea of his powers, or that supernatural beings even exist...
