There has always been tension in "the blind house," where Valentina lives with her mother and grandmother in the Italian countryside. Valentina's pious grandmother often hints at a family curse, while Valentina's mother scoffs at superstition; it's one of the battlegrounds on which they fight to control Valentina's upbringing.

But in the summer of 1996, when Valentina is twelve, she gets her period for the first time-and the curse suddenly becomes frighteningly real. Blood leaks from the walls; the house and farm are overrun with frogs; the kitchen crawls with flies. Valentina is certain that she has brought catastrophe to her house and its inhabitants.

In this propulsive coming-of-age novel, of mother-daughter relationships and painful family legacies, Valentina is forever changed by the events of one terrifying summer.
