Intermundane (гет)

Hermione reaches out to the mysterious owner of Silverleaf Apothecary for help when she realizes a deadly, magic-stealing pandemic is upon the Wizarding world. Severus Snape disappeared from Wizarding society fourteen years ago after he'd recovered from his injuries. Now Hermione is trying to drag him back into it. He agrees to assist, but only if she quarantines at his home while they work on the project together. As they discover ways to treat the illness, Snape realizes he might not be so solitary, and Hermione gets to know the man behind her former professor.
