Who will Orla and Jo turn to for help when they really need it? Haresden is in chaos! From destroyed troll cairns to a bewitched flock of sheep being mesmerized by a mysterious moth that may be Mamos familiar. Maybe the girls could enlist the help of a murder of crows and their leader, Caractus, who owes Jo an old life debt? It just might be time for Jo to lead Orla into something new, and strange, and magical. That is, if these corvids can even be trusted.
