I love those books. Please note that I´m right in the middle of the last Kane one....so no spoilers please.
Absolutely! My wife and I are reading right along with our kids. We love Rick Riordan. Finished the first Percy Jackson series, plus the Kane Chronicles. Now we're passing around House of Hades, his latest.
He's obviously done his research into the various mythologies, incorporating them into the storylines in innovative ways. The books are fun to read, and capture the speech patterns of teens very well. And the chapter titles are some of the best parts. My daughters' favorite is, "Men Ask for Directions, and Other Signs of the Apocolypse".
And they absolutely adored Sadie Kane. Not sure whether I should worry or not...
