Tethered In Shadows (гет)

At 21, Harriet Potter has already seen more war than most Aurors twice her age. When she’s assigned a month-long duty at Hogwarts, she doesn’t expect to find Severus Snape more vexingly magnetic than ever.
Severus, no longer burdened by war and guilt, finds Harriet’s arrival disrupting his peace in the most infuriating and delicious ways. Harriet has changed: she’s confident, reckless in the way only someone who survived death twice can be, and she wants him—the sharp mind, the dark humor, the way he looks at her as if he could strip her down with his eyes. And Severus takes delight in her interest, refusing to let her games remain innocent.
