"There is no logic to love.
Forbidden or not,
you don't need a reason to love someone."
Rose Weasley hates James Sirius Potter's shameless guts but she can't get enough of her cousin's infectiously radiating presence... So much so that she begins to question her feelings for someone who is supposed to be a brother figure to her, but doesn't act like one at all.
T for cousincest.
