Lulu's Hat

Lulu's Hat by Meddaugh, Susan. hardcover edition. ISBN: 0046442152778.

In True Magic Families, a single member of each generation was born with the magician’s touch. Real magic. It was a genetic quirk that no one could explain. Either you had it or you didn’t. But Lulu could never be the one in her generation gifted with magic, because Lulu was adopted. Nonetheless, Uncle Jerry the Great lets her have her chance to join him for the summer as his assistant, just like all of the other cousins. All she needed to do was warm up the crowd with a few simple tricks, but Lulu was all thumbs?until she discovers a dusty, old hat in the botom of her uncle’s costume trunk. All sorts of strange things start to happen, and soon Lulu’s unpredictable nature leads her on an adventure deep into Magic Space.
