Rick Riordan’s next novel has fans buzzing with theories, and I’m all in on the speculation. Many believe he’ll dive deeper into Norse mythology, especially after the success of 'Magnus Chase'. Some think he’ll introduce a crossover between the Greek, Roman, and Norse pantheons, creating a massive, interconnected universe. Others speculate he might explore lesser-known mythologies, like Celtic or African, to bring fresh stories to life. Personally, I’m hoping for a return to Percy Jackson’s world, but with a twist—maybe a new generation of demigods or a darker, more mature storyline. Riordan’s knack for blending humor, action, and mythology keeps fans guessing, and I can’t wait to see where he takes us next.
