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.

Harry Potter is involved in a potions accident which ends up with him de-aging to a foetus and implanting in the womb of Severus Snape, who is a bearer. Severus can no longer spy, to the chagrin of Albus Dumbledore, but he uses it as an opportunity to show his true self, the person he has been forced to hide for over twenty years.
And maybe, just maybe, he can save his students from the pressures of war.
Mentions of physical, emotional and sexual abuse that various characters are trying to heal from. Many characters being bashed.
I don't own Harry Potter.
