I'm eagerly awaiting House of Hades,
I just need my 9 year old to finish it, so I can read it! I've loved all of the Percy Jackson & The Olympians/Heroes of Olympus
books. They are a great mix of mythology, adventure, and humor.
I do miss the humorous chapter titles in The Heroes of Olympus
The Kane Chronicles
, to be honest, hasn't grabbed me. Red Pyramid
was just okay for me and I put down The Throne of Fire
a while ago and never felt the need to pick it up again. I can't tell if it's the dueling narration, the plot, or the use of Egyptian mythology that makes me feel this way.
That being said, if he's next working on a series of novels with Norse mythology, I'll definitely give them a shot!
