I want to be very careful how much I give away about my YA dystopian novel Night of the Purple Moon. But I think this much is safe to say: Earth becomes a planet of young teens and children—virtually overnight–after space dust from the tail of a comet penetrates the atmosphere. The dust contains germs that attack the hormones which come at the onset of puberty. Older teens and adults have these hormones in abundance. Children and younger teens do not. Yet every one of the survivors of the lightning fast epidemic has a ticking time bomb inside of them: growing into adolescence.
