For parents

What Parents Should Know

The fantasy premise begins when the sisters' parents disappear and the eight children decide to live alone while keeping adults from finding out. They face household mishaps, suspicious neighbors, villains, magical danger, and the possibility that social services will separate them.

The peril and final battle are written for elementary readers and balanced by wordplay, illustrations, and the sisters' teamwork. Children who are sensitive to missing-parent stories may still find the continuing mystery more intense than the playful presentation first suggests.
