What if Sky had another sister? What if she was an animus? This is the story of Crimson and Sky's adventure with Wren. The characters other than Crimson are Tui T. Sutherland's. This story is dedicated to Sweet_Wing_Queen101 who helped me find my love of fanfictions! I've moved to ao3 (IAmDeathFearMe) and might rewrite this but probably not. This story has been discontinued as I am very unhappy with the way I wrote it, but it's up for adoption if you want.
