Ermintrude and her great-granddaughter Minnie visit the wizard who lives on the hill, hoping he'll invent a spell to make Ermintrude's secret wish come true. Things, however, don't go quite according to plan... A little story in verse, sometimes funny, sometimes sad, that can be read on two levels. The first describes a series of magical mishaps by a wizard whose spells don't always come about in the way he intends. The second is a gentle metaphor that works as an alternative to a religious or atheistic explanation of where we go when we die, but both end with Ermintrude's secret wish coming true. Ages 3 - 93
