The Theory of Transference (смешанная)

In 1998, Lord Voldemort captured Harry Potter, won the war against the Muggles, and transformed Great Britain into Britannia Magica. Given the choice between rotting in a cell forever and joining him, Harry surrendered and took the Mark.
Five years later, Harry lives captive in Malfoy Manor while the war with Europe rages on. He kills his time by pacing the gardens, smoking with Draco Malfoy, and occasionally indulging in harder substances.
Life changes again when Voldemort discovers a ritual that could potentially transfer Harry's magic to another wizard. To test this ritual, he gives Harry to Severus Snape.

Severus moved to the bed. What a hero, he thought, staring down at the boy. The Chosen One, the Boy who Lived.
Such crap. He was a child, even at twenty-three.
A stupid, wretched, shamefully daft, monumentally unlucky child.
“Lie down,” Severus told him.
