I want to call this a 5 star, but I spent much of the first half wishing something would happen or it would pick up and move faster, but I still loved it overall. The only thing I really don't like about this series/book is that we don't know how it all ends yet!! 
 Neryn continues her journey learning what she needs to become the Caller that everyone hopes she will be. She must find the Hag of the Isles in the west, and wake the Lord of the North. Both tasks are immense and full of challenges. And, oh yeah, she has a short time frame in which to meet with and learn from all 4 of the Guardians. 
 I liked that her travels were with Tali this time, so we got to know her better and see the interaction between the two women grow from hostile and cold to friendly and companionable. The challenges faced by two women traveling alone over the countryside were different than those faced when Neryn traveled with Flint in Shadowfell. Both the situations and the women's reactions to them reflect their stress and fear of discovery. Flint is less of an influence in Raven Flight, though he does appear at key points on Neryn's journey. 
 But the end? Man I wish I could have skipped it or jumped right in to the third book. It cannot come fast enough.
