Jacquelyn was trying hard to focus on her studies in 6th year, but Sirius Black is such a pleasurable distraction. Emotions run high in Hogwarts as they make some self-discoveries and see in times of strife, love is the only thing you can depend on
Plenty of Lily/James and for Severus/Lily fans please don't be disappointed when I say there isn't any. Takes place during Marauders Era, mild-to medium lemons in later chapters hopefully and some language so the rating is an M.
(I have poor grammar, if there are mistakes occasionally please overlook)
Enjoy!
