Hi! Searching for the title and author of a book, probably a children's book, about a character named Giovanni who learns how to use a magic wand. The ending is sad. Probably published in the 1990s or before.

A long shot - Wizard of Windsor Island: Giovanni's Missing Boat by John M. Kraus?

Setting - Earth (modern or historical) or a fantasy world?

Martin, are you still looking for this or did you find it?
