Respect Your Ghosts — John Bemelmans Marciano

Welcome to Benevento, an ancient town famous for its witches!

The children of Benevento have to be careful and clever to evade the clutches of such witches as the Manalonga, the Janara, and the Clopper, who hide in wells and under bridges, fly at midnight, and play tricks during Mischief Season.

Five cousins -- Primo, Emilio, Rosa, Maria Beppina, and Sergio -- share adventures and narrow escapes, and discover astonishing secrets as they outwit the witches in each exciting story.
