Fire in The Dungeon

"This is madness," Snape muttered, his thumb tracing the delicate line of her jaw. "We're playing with fire."

She opened her eyes, her gaze meeting his with a fierce intensity that left him breathless. "Then let me be the flames that set your heart ablaze."

Severus Snape, the cold and bitter Potions Master cloaked in secrecy and duty, meets his match in Andromeda Potami-a devastating beauty with magnetic warmth that draws everyone to her. Beneath her charm lies a woman with a mysterious past, guarded by a web of secrets even Snape cannot unravel. As dark forces gather at Hogwarts, their unlikely bond blossoms, pushing Snape to confront feelings he long buried.

But what truths is Andromeda hiding? With her life entangled in his, Snape finds himself questioning everything he thought he knew, and asking himself the question: can time heal all wounds?

The slowest of burns because no way Snape has a crush for 20 something years and moves on quickly.

Written from Snape's POV and will mostly follow the canon events from POA to Deathly Hallows. Strap in kids, this will be a long one. ;)
