Set at the start of book five. The ever-busy Dumbledore is a little delayed in sending that howler to Petunia, and so when Vernon insists that Harry needs to leave the house as he's clearly a danger to the family, Harry is packed and down the road with no protest, causing the blood wards to break. The Dursleys instantly become a vulnerable target for Death Eaters, and Harry himself is snatched by a Death Eater, but it's Severus Snape and this is coming from a Severitus writer so you've likely already figured out where all of this is going.
