Harry met Holly when she was two - abandoned in the park by her mother. Unable to leave her alone, he stayed behind to keep her safe. Over the years, they became as inseparable as brother and sister.
When Harry found out he was a wizard, he was happy to find that Holly was a witch too, and one day, she would enter his new world with him.

Finding out he was a father to a nine-year-old girl, Severus Snape didn't hesitate to bring her home. His daughter belonged by his side, after all. Finding his daughter preferred Harry Potter over him was a travesty the Potions Master was not going to tolerate.

Somehow, Severus had to make his daughter see Harry Potter as he did - worthless, useless, hopeless.

Severus Snape never expected to survive the war. But here he is, one year after the Dark Lord's final defeat - one year after Harry Potter's disappearance, presumed death.
As the boy's Last Will and Testament is released, Severus finds himself facing the gravity of his actions, in the form of the secrets hidden inside a cherry-wood box, and scribbled across a leatherbound journal.

Inspired by "Like poppy and memory" by lesyeuxverts, here on P&S.
