Rhiannon Lassiter's second novel, set a year after the events in Hex, is a crucial element in the trilogy . Following on where Hex left off, it follows Raven and Wraith's expanding group that the government have dubbed terrorists . Still determined to bring the truth about Hexes to light , the group are forced to join with a gang of freedom fighters called Anglecynn when an error of judgement on Raven's part results in tragedy . As well as the original characters from the first novel , Shadows introduces several new ones . This book also focusses on Raven as a person in a way that neither the first or third book does , and is probably the one in which she appears most human. This is an excellent book and vital to the series . Lassiter's writing , while by no means poor to start off with , gets even better in this . I definitely recommend it to anyone who liked Hex.
