I had a hard time with Stesichoros. Stesichoros did not seem to flow with Geryon's story. It seemed unnecessary and out of place. I would have enjoyed the novel more without beginning and ending it with Stesichoros.
I enjoyed that Geryon was a monster. It made his character more interesting and made him easier to relate to. I think everyone sees themselves as a monster at some point, alienated in some way (perhaps not as alienated as Geryon feels). I was happy for Geryon on page 144 in his conversation with Ancash:
There is one thing I want from you.
Want to see you use those wings."
Someone finally recognized that Geryon is not just unique, but special. He needed that compliment to give him confidence. I guess I just typically like stories with happy endings, and this ending made me think that Geryon was going to go places and become an exciting, independent, and confident little monster.
