I swear I read this fic recently but I can’t seem to find it now. In the fic Derek and Stiles are mates. One day Derek follows Stiles scent to I think the police station. He walks in only to find him as a kid reading a book. They discuss the book before Stiles gives it to him to keep. Derek then has to stay away from him until he’s older to solidify the bond. They meet again years later and stiles discovers that Derek kept the book all those years. That’s all I can remember.
