After I found out that RAVEN FLIGHT was the sequel to SHADOWFELL, I was a little worried that I would be lost reading book two before book one. My fears were not realized. While I am sure my experience would have been more complete, RAVEN FLIGHT stands alone quite well as a fantasy novel. (Although I will be reading SHADOWFELL as soon as I can.)When this story begins, Neryn has reached Shadowfell among the rebels and is regaining her health and strength. She is learning about her powers as a caller who can command the fae and wrestling with the boundaries between what she can do and what she should do. The rebels are slowly building the support they need to defeat the evil King Keldec when they learn that they have a deadline. One of the eight chieftains will throw in his support for the rebels if they are ready to act in eighteen months. Neryn needs to find the three Guardians she has not yet met and learn from them so that she will be ready. She also needs to enlist the aid of the fae in the kingdom to help with the revolution. She and Tali go off looking for the Hag of the Isles while dodging Keldec's Enforcers and other perils of the road. They need to find her, learn from her, and then go on to find the Lord of the North before winter.All the while, Neryn is thinking about her friend and love Flint who is an Enforcer who is acting as a double agent trying to balance being the king's best friend with the needs of the rebels. She is worried about him and often sees him in her dreams. They do manage to cross paths a couple of times during the course of this story too. The language is lush; the world building interesting; and the various Good Folk interestingly portrayed. The story is exciting and it was wonderful to watch Neryn grow in her powers and in her determination to overthrow the tyrannical King Keldec. I can't wait for the next volume to see how the battle goes.
