   Summary

   Julia Thorne and Severus Snape traded first place in Potions like a sport. Every time one edged ahead, the other made sure it was subtly noticed. The rivalry between them was addictive, but Potions was the only place their worlds met. The moment class ended, they walked out and peeled apart.

   Everything changed during the summer holiday before their final year. Whilst working together in the Apothecary storeroom for the annual audit, their rivalry softened into something deeper as they learnt more about each other, finding a rare connection bonded by mutual talent... and want.

   For Julia, the seventh year is difficult because secrets are uncovered, concealed, and shared.
