Children love reading stories about holy fools! A holy fool is a madman. That is, someone whose mind is crazed! Holy fools are ascetics who pretend to be mad for the sake of Christ, which is why we call them "fools for Christ." And because children are also little madcaps, they love them very much! Very, very much! Up to the sky!

The sixth book in the series When the Sky Laughs is dedicated, like the fifth, to the holy fools. It is an inspired narrative for children, but also for older readers.

The protagonist Trelagiasis meets the holy fools:

Saint Maria Skobtsova,
Saint Sophia of Kleisoura,
Papa-Photis Lavriotis
Saint Andrew
Saint Basil
Saint Serapion the Sindonite
