Rick Riordan has another Greco-Roman series coming up. The first book will be out this spring, and the lead character will be no other than Apollo. The god of the sun was first introduced in "The Titan's Curse". He seemed like a misunderstood lad. Some would be reminded of Rob Kardashian, which Riordan wouldn't object at all. After all, the author adopted Greek mythology to popular culture.
Expect "The Trials of Apollo" to be a follow-up on Percy Jackson and the other demigods. Not that Apollo must star in his own series, but Riordan depicted an interesting Olympian. He don't take himself too seriously, even if some readers saw a self-indulgent teenager. Many will read "Percy Jackson and the Olympians" once more, even recalling their favorite characters. Don't be surprised if they were women. (If not for Eris, then Homer might not have penned "The Iliad".) Here are your favorite Olympians:
Medusa (The Lightning Thief). She was a middle-aged lady who lived far from the bright lights of the Big Apple. She would fancy antique items. Riordan didn't depict her as the uncaring landlady from Brooklyn, who made fun of her female tenants. And there would be statues of men in the basement. This Gorgon must adopt to modern times, which could be a scary thought. Percy Jackson found this out before he looked into her eyes.
Circe (Sea of Monsters). She owned a resort island in the Caribbean, and her guests were unaware that they bought a one-way ticket. (Riordan might have based it from his traveling experience.) Circe could be the perfect host, but better not be curious about her place. They might end up like Jason.
The Sphinx (The Battle of the Labyrinth). Who would have thought that the Sphinx loved useless information? Those who failed her test must be killed. This was Riordan's homage to Ancient Egypt. They built the Great Pyramid of Giza, among many other things. They knew too much, and put it into good use. Ask Thutmose.
Calypso (The Battle of the Labyrinth). She could have been the bitter heroine in a romantic novel, but Riordan depicted her as a patient soul. She didn't hold a grudge against Percy (after forgetting her). Leo Valdez turned out to be the better man.
Tammi and Kelli (The Battle of the Labyrinth). These cheerleaders were empousai, monsters that prey on young men. Megan Fox might have thought of them while filming "Jennifer's Body".
