Ten years after the war, Hermione Granger has mostly dealt with her traumatic past. Despite a recent divorce (and the cursed scar that still troubles her), she's feeling good about her life. Head of the recently-renamed Department for Magical Creatures, and surrounded by a group of friends she's sure will be with her for the remainder of her life. Everything seems to be working out (mostly) as she expected. Until Narcissa Malfoy shows up in her office one day, asking for help investigating a lead that says her sister - Bellatrix Lestrange - might not actually be dead.
