I Ching, You Ching

I Ching, You Ching is a magazine. Prunella was reading issue 7 when Brain talked with her about his secret from kindergarten.

Muffy also picks number 7 off the rack in Prunella Packs It In after discussing Chalice of Malice from Henry Skreever (book series) with Prunella in the library.
