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.

Third year brings new troubles to Hogwarts, but none more than Harry Potter with the breakout the Dark Lord's right hand man, Sirius Black. Determined to finish what his master failed, Harry is sent back to the Dursleys where he can be safe within the blood wards and not allowed to visit the Weasleys at all nor contact his friends. To make sure of this, Hedwig is forbidden from being taken back to the Dursleys, yet after Sirius is sighted near Privet Drive, Professor Snape is forced to take control of Harry as an apprentice. However, when Snape arrives at Privet Drive, he discovers that Potter is missing. Is it Black that kidnapped him? Is it someone or something else more sinister? Harry is found in an unlikely place and taken away, forbidden from contact with his friends as he is thrust into the role of apprentice. Yet amidst these troubles, Harry discovers something about himself and a hidden crime that only a murder and his best friends know, something that may change Harry's future for the better...or the worst.
