Ghosts in the Quarry

It's said that twins are double trouble—but what about quintuplets?

Twelve-year-old Dawn Rodgers, the firstborn of five, loves getting lost in books. She's always hiding in a corner, trying to avoid her boisterous siblings. But one day, one of her brothers claims to have seen an invisible creature near the abandoned rock quarry. Dawn is not impressed. How can one see someone invisible?

Out of curiosity (which proverbially killed the cat), she goes along with the others to explore the quarry, a place of rocks, sand, water, and little else. And she has to admit that there is something hiding there. After all, she's the specialist for hiding. Now the five children are eager to find out who or what is haunting the quarry.

Naturally their imaginative ideas get them into trouble, and if they don't act fast they might not see their home, their parents, their friends ever again… or they might even end up like the proverbial cat. What can Dawn do to save her siblings?
