At the end of the "Prisoner of Azkaban" year, Fred, George, Harry, Ron, Hermione and Ginny were given detention by Snape. They have to organize potions ingredients. Percy is supervising, but when Bill and Charlie turn up the kids knock over the bottles, a few ingredients mix and an explosion happens. Snape rushes in to find six babies/toddlers and three children: each person has had about ten years removed from their age. Thankfully, it was the last week of school. The nine go to the Burrow and Mrs Weasley looks after them, with some help from Percy, Charlie and Bill. Ginny is nearly two; the Golden Trio are three; the twins are nearly five; Percy is 7; Charlie 11; Bill 13. One more twist: somehow, Hermione and Harry have turned red-headed, Harry identical to Ron except for his scar (the two of them have both changed a bit to look more like the other one’s original, and now they were an identical mix), and Hermione pretty similar – and all the kids think that they are triplets and always have been. Everyone’s mind has been wiped, and they think that this is normal.
Can Molly cope with having nine young ones to look after? Can they all cope with being a young family again, this time with two extras? Will they change back in time for school? And most importantly – will Mrs Weasley have enough chocolate milk?
