I can't say this book was "Oh, Wow Awesome" for me, but I did enjoy listening to it. I especially love that there were two separate voice actors since the narration switched between Sadie and Carter.
I really like the sibling relationship between Sadie and Carter, especially since they start of a little estranged. It's not the type of relationship I get to read very often and I love what Riordan's done with this one. Sadie and Carter start to respect and truly care for each other throughout the story and it never felt forced.
There's definitely a good bit of lore to take in with this one. I felt confused and lost a few times, but it wasn't too big a deal. And part of that was probably me being a bit spacey anyhow. Still, I really liked the Egyptian lore since I can definitely say it's not something I've read before.
In typical Riordan fashion, the adventure takes place in multiple countries and places within them, all in the course of about a week. This means there's never really time to be bored.
The Nutshell: I would recommend The Red Pyramid to anyone looking to dive into a whole new world of adventure and mythology. There's plenty of action, humor, and heart to keep you entertained. I look forward to seeing what the second book brings!
