Out of Ashes (слэш)

For twenty-three years, Severus Snape had been an excellent actor. A pity the curtain fell at the most inopportune moment.
Now he has serious trouble with the Ministry, a delicate situation with his colleagues, and one extremely persistent eighth-year student who’s certain he understands metaphors of rebirth.
A story about how some secrets are better kept forever. And about how Potters never knew when to stop.​​​​​​​​​​​​​​​​
