If there's one thing James knows, it's that he loves Lily Evans. Until a potions accident makes him realize his soulmate might be someone else...

He shook his head in confusion. No. This isn't right. I'm in love with Lily. I've always been in love with Lily. I can't possibly have feelings for this...this...interloper.

James isn't the only one affected by the potions accident! Severus, Regulus, Sirius, and Remus have found their soulmates, too.
