This is a beautiful and melancholy book. Robert Murphy's grasp of golden eagle psychology is believable, and his descriptions of flight are better than the ones in Jonathan Livingston Seagull. When I was a child, this book got me drawing golden eagles and thinking about them.
Although the eagle in the story is called Kira (note the i), Robert Murphy's evocative prose is partly responsible for my later becoming a fan of actress Kyra Sedgwick.
Despite having been written before their time, this book also pairs well with many of the Tony Hillerman mystery novels featuring tribal police officers Joe Leaphorn and Jim Chee. Leaphorn and Chee work in what might be called "golden eagle country," and they know it.
I didn't realize that this was a fictional story about an eagle so I began reading with trepidation, but I was overall very pleased and drawn into this story. It was well written and very interesting. I'm a falconer myself and the facts were all correct. I would say that it would be a great nature story to read with your children, but there are a few issues that make me cautious about that. 1. It was written in the 60s so there is a lot of shooting of wild animals that may be upsetting. It's a part of life that things are killed but for kids who aren't ready to deal with it, be careful. 2. The ending is very sad. The events can definitely be interpreted as a warning to respect and cherish nature but I was a bit let down. I would have enjoyed if the man who owned the cabin had taken Kira up for falconry. Considering this was written by a falconer I was expected it to go in that direction. I also expected the story to have Kira eventually raising her own nest but she didn't get that chance. 3. There is a LOT of lengthy description about the mountain range and other natural features that can get quite lengthy.
I enjoyed all of these features and understood them in their context, but for a kids' recommendation they give me pause. Overall I enjoyed this read and think it's a worthwhile recommendation. :)
