Chapter one: The First Day

Y/n is James Potters twin sister. The only female marauder. She is like her brother in many ways that she wont admit she is clever, talented, mischievous, and they're both cocky smartasses with a sense of humor. Another way she's like her brother is that they both instantly took a liking to a certain book-obsessed chocoholic.
Remus Lupin was a quiet boy who liked books, chocolate and sweaters. Nobody suspected that he would be keeping a secret from everyone. Who knew that the shy, awkward, smart Gryffindor boy was a werewolf? What will Y/N do when she falls in love with him? What will he do? Does he feel the same? What will James think?

Warning: Some swearing and sexual innuendos.
