16 Going On 36 (слэш)

Knowing that he is dying, Dumbledore takes it upon himself to take out Voldemort as soon as possible. That should have meant life was easy for Severus, especially when all of the Death Eaters were rounded up. Without an alternative however, Severus became public enemy number one, with many demanding he go to jail himself. That Severus could handle, what he couldn't handle was waking up one day in the body of his 16 year old self. Dumbledore said he would look for a cure so all Severus had to do was make it through the school year. Unfortunately that also meant that he would have to deal with Harry Potter.
