Reading this took me a while but now I've done it and it was awesome. I personally loved the Greek Gods more but it's because it had more weird and intriguing stuff going on because, well, it focused on the gods. Percy's narrative was great once again, I got a good laugh of all the mentions of modern stuff thrown into the myths. Orpheus playing "Shake It Off" and the gods getting confused of the time period etc. Hilarious! I really liked Percy's mentions of his friends. Annabeth seems to be around him a lot and I'm not complaining about that! 
 How do I wish that text books were this entertaining.
