I guess I'm on a bit of an island here. I thoroughly enjoyed this story. I felt the pacing was perfect for an audio story. I don't believe it would have worked in print or with a lessor narrator. I don't believe this was an elf story. This was a Fae story.
As for the abrupt ending, I liked it. It gave me a feeling of more to come. Whether I hear that story or not, whether it is ever written or not, that story is there, waiting to be told. There was a bit of world building done, and an outstanding job of character building. Maybe I'm just a little bit too old school, but I like fantasy series. Give me a strong cast, flawed though they may be, and let me see them develop. Owl has the potential to do just that. We heard his back story here. Now he is on the threshold of adulthood, or whatever the Fae equivalent is. He has seen that there is more to his world, and is no longer a naive youth. He still has much to learn, but it is now his time to seek that knowledge, not wait for someone to point him in the right direction.
Of course, that's just my opinion.
