When Albus Potter and Rose Weasley start their first year at Hogwarts. they're targetted by what seem like malicious practical jokes, which invoke the name of the Dark Lord. Even after so many years, who would joke about a man who caused so many deaths. The wizarding world may again have to face up to the issues which still exist and may again prove divisive.
Thanks to MrsJaydeMalfoy for her help with the summary.
