*I received a free review copy in exchange for an honest review of this book. 

UNTETHERED SKY is a story of one-sided devotion between a rukher and the roc who can never love her back, training to hunt manticores. The relationship Ester builds with Zahra, her roc, drives much of the narrative. It's all from Ester's perspective, as Zahra is a large bird who is unable to put words to whatever her thoughts might be on the matter. There's a contemplative air to the story, as Ester is telling this story from some unknown point in the future, looking back on her life in stages. I love stories of training, where someone is navigating the small moments of mastering a skill and figuring out how to get even better. Ester is close companions with one of the other rukhers, bonding over the process of training and care of the rocs which are the center of their lives. She becomes aware of the place rukhing has in the lives of other people, their nature as important tools for a very specific job. The worldbuilding is focused on the details of rukhing and the care of rocs, the similarities to falconry and very important differences with a creature far larger than her handler. 

I enjoyed this and I love the ending. The details of the manticore hunt are gripping and I didn't want the story to be over but I'm very happy with how it fits the overall narrative.
