New York Times Best Selling Author Rick Riordan told Fox 2 fans of Percy Jackson may see some similarities between Percy and Magnus.
"He's similar to Percy Jackson in the sense that he is a demi-god," said Riordan. "He is the son of a Norse god."
The former middle school teacher's stories often weave modern reality with ancient mythology. While most of his books are aimed towards pre-teen and teen readers, his fan base spans generations.
Riordan wasn't involved with creating the movies based on his books, but he said he's grateful for their success.
"I haven't seen them," he said. "I really don't know anything about them, but they brought a lot of people to the books and I do appreciate that."
Riordan said he often hears from his fans that they relate to the characters in his books.
"Fantasy, I think, lets kids explore some really heavy issues that would be kind of uncomfortable and threatening if it was done in a more realistic setting."
Riordan created the Percy Jackson character for and based on his son, who in elementary school was diagnosed with Attention Deficit Hyperactivity Disorder and dyslexia.
Riordan will take readers back to Percy Jackson's world a final time in the spring of 2016 with a book featuring the Greek god Apollo. The second book in the Magnus Chase & the Gods of Asgard series is due to hit store shelves in the fall of 2016.
