The year is 1976, and life at Hogwarts is growing more complicated by the day. Lydia and Stiles are keeping secrets from their friends, Scott, Isaac, Malia and Kira are keeping secrets from themselves, Allison and Danny are finding and keeping secrets that no one knows, and outside the castle walls, a war is slowly starting. In other words, the Teen Wolf x Marauders Era crossover that no one asked for, featuring drunk kisses, invisible kisses, accidental kisses, stolen kisses, truth or dare, quidditch, tiny pink elephants, a dragon trainer, more gay than you can poke a stick at, and Theo Raeken getting kneed in the balls (a lot).

Lydia Martin is simply just a nerd. Not a cliche nerd with glasses or braces. But she's always relied on school as her lifeline. Well, school and Allison Argent. Allison, even though she's the school president, is her best friend. Despite the fact that Lydia is involved in every club known in Beacon Hills Preparatory High School, she has never made friends other than Allison. Stiles Stilinski is Beacon Hills' bad boy, alongside Scott McCall and Issac Lahey. He's a playboy, and in a boarding school, it's not hard to come by those. Dark hair, carmel eyes, what's not to like! Putting aside his cocky attitude, his bitchy on-and-off girlfriend, Malia Tate, and the way he treats people, he's perfect.  Lydia Martin has known Stiles Stilinski since the third grade, and that's when she first fell for him. He was funny, smart, and creative. They were once friends but as they grew up, they became more distant. She's always gone to the same school as him and admired him from afar. However, something changes in him. Stiles Stilinski asks Lydia for a favor and because she wants to spend every moment with him, she agrees.  And they make a deal.
