Calista Snape, daughter of famed Death Eater Bellatrix Lestrange, is distant, and spiny, and deeply untrusting; but then, so is the man that has mysteriously shown up, calling himself her father. Against all odds, Severus manages to reach the frightened, traumatised little girl he's suddenly found himself charged with protecting, but neither of them is prepared for the explosive manifestation of Bellatrix Lestrange's desire to escape Azkaban, at any cost. After the Dark Lord's fall in 1981, more than one child was lost in the spoils of war. Six-year-old Calista, the daughter of the Dark Lord's most infamous and fanatical follower, Bellatrix Lestrange, has been left in an orphanage by her mother's cousin Sirius Black, following her rescue from a mother that only wanted to twist her to the Dark Lord's purpose. The staff at the orphanage consider her both a lost cause and a Squib, but it may take a forgotten, rejected man to save a forgotten, rejected child. For his part, Severus Snape has enough to regret without dwelling on his brief, haunting affair with the Dark Lord's most quixotic servant; but he decides to see, in the aftermath of her arrest, if he can locate her missing daughter. Instead of answers, he finds a haunted, irrevocably damaged child with his eyes and his ghosts, and he knows at once that he cannot leave her where she is. Above all, a realistic Snape's daughter story, as well as an honest depiction of recovery and PTSD, and an in-depth exploration of the mental arts of Legilimency and Occlumency.
