The Dark Prophecy by Rick Riordan, published in 2017, is the second book in The Trials of Apollo series. A continuation of Riordan’s dynamic and humorous take on Greco-Roman mythology, the story follows the disgraced sun god Apollo—now cast to Earth in the mortal form of a teenage boy named Lester Papadopoulos—as he embarks on a quest to reclaim his godhood. Following the events of The Hidden Oracle, Apollo journeys across the American Midwest to find the next lost Oracle, uncover the mysteries of the “Dark Prophecy,” and confront the looming threat of the imperial Triumvirate led by ancient Roman emperors.
Plot Summary
When the once-golden god Apollo crashes to Earth as a pimply mortal named Lester Papadopoulos, his fall from Olympus comes with more than lost powers – it comes with a long list of enemies and impossible prophecies. Six weeks after escaping New York, Apollo continues his punishment by Zeus, forced to endure life as a teenage boy without any divine perks, except for his lingering arrogance. Alongside him ride Leo Valdez, the snarky, flame-wielding son of Hephaestus, and Calypso, the former immortal daughter of Atlas, who is now mortal herself, without her powers, and adjusting rather poorly to human fragility and modern Midwestern winters.
Their bronze dragon Festus crashes them into Indianapolis, an apparently harmless city that soon reveals a lurking danger beneath its cheerful façade. Apollo senses the weight of prophecy, feeling the pull toward the next Oracle, one he must secure if he is to have any hope of reclaiming his godhood. But Indianapolis has fallen under the sway of one of the Triumvirate – a shadowy cabal of reborn Roman emperors bent on subjugating or destroying all that remains of the old gods’ influence.
Their first welcome comes in the form of blemmyae – creatures with faces in their torsos and an unsettling fondness for polite small talk, violence, and casual enslavement. Apollo, Leo, and Calypso barely escape their attack thanks to a mysterious ghost and the intervention of Emmie and Josephine, two women who live in a mystical, ever-shifting safehouse known as the Waystation. Hidden in an abandoned train station, the Waystation is sentient, sprawling, and full of secrets. Emmie, as Apollo recognizes with painful surprise, is Hemithea – a girl he once made immortal thousands of years ago, who now lives a mortal life alongside her partner Josephine, far from the gods’ grasp.
The trio learns that the Oracle they seek lies within the Cave of Trophonius, guarded not just by prophecy but by madness. Trophonius, once Apollo’s own son, was turned bitter and monstrous by the god’s neglect and the cruelty of fate. Now he demands a toll in the form of a terrifying ritual – one must enter the cave, face the hallucinations it births, and return with the truth or not at all. Before they can even contemplate this, Apollo and his companions are drawn into the lives of the Waystation’s residents. Georgina, a young adopted daughter of Emmie and Josephine, has gone missing after visiting the Oracle. Her absence has left the Waystation scarred and her parents desperate.
Apollo, driven by guilt and a surprising surge of empathy, vows to retrieve Georgina and face the Oracle himself. Meanwhile, Meg McCaffrey, Apollo’s unpredictable and emotionally complex demigod master, re-enters the stage. Torn between the control of her cruel stepfather – Nero, one of the Triumvirate – and her conflicted loyalty to Apollo, Meg becomes both an adversary and a child in need of rescue. Her stepfather’s grip on her is terrifyingly complete, and she is ordered to either bring Apollo in or kill him.
With the help of Leo’s ingenuity, Calypso’s determination, and the Waystation’s magic, the group makes their way toward the cave. But the Emperor Commodus, another member of the Triumvirate and Apollo’s old foe, is tightening his hold on the city. Once Apollo’s former trainee in the gladiator arenas of Rome, Commodus now rules Indianapolis like a stage – he stages public executions and slave parades, basking in applause. He wants Apollo returned not just as a prize, but as a trophy to humiliate, break, and parade through the streets.
The journey to the Cave of Trophonius is no straightforward trial. Apollo must not only endure physical challenges and hostile minions but reckon with what he was as a god – proud, unfeeling, and distant. The cave itself is a nightmare. With the help of the ghost Agamethus, the silent brother of Trophonius, and their talking arrow guide, Apollo enters the cave, surrendering himself to its madness. The Oracle’s revelation writhes through his mind – a prophecy not of victory but of coming loss, and of another child of Apollo suffering a cruel fate. The knowledge wounds more than any blade, and Apollo barely escapes with his sanity.
Georgina is rescued, but her mind is fractured from her time in the cave. The prophecy she babbles is incomplete and fragmented, haunting in its warning of what lies ahead. Apollo’s visions of Nero’s luxurious Manhattan penthouse and the manipulated Meg paint an increasingly grim picture. The war with the Triumvirate is more than a clash of armies – it is a conflict of past sins, broken loyalties, and the consequences of divine neglect.
To escape Indianapolis and keep the Oracle’s secrets safe, the group must face Commodus in his own twisted arena. Apollo, unarmed and humiliated, is forced into battle, his mortality and fear exposed. But even without his divine strength, Apollo begins to understand courage in its truest form – not born of power, but of choice. With assistance from his friends and a well-placed trap, Commodus’s operation is brought down. For now.
The Waystation endures, a fragile sanctuary between storms. Calypso begins to heal. Leo, ever-resourceful, reclaims Festus. Georgina, slowly, begins to return to herself. And Apollo, still Lester, remains in exile, the weight of his son’s sorrow and a prophecy of fire, betrayal, and sacrifice lingering on his shoulders. As the road west beckons, so does Meg – not as a master, not as an enemy, but as someone Apollo might yet save. And perhaps, through her, save himself.
Main Characters
- Apollo (Lester Papadopoulos) – Once a divine Olympian god, Apollo is now bound in a mortal, acne-ridden teenage body as punishment from Zeus. Vain, witty, and narcissistic—but also evolving—Apollo grapples with mortality, pain, and the emotional burdens of his past misdeeds. His journey is one of humility and redemption, offering both comedic and heartfelt moments.
- Leo Valdez – A child of Hephaestus and a returning character from The Heroes of Olympus, Leo is a brilliant inventor with a gift for mechanics and fire. His loyalty and sense of humor ground the group, while his deep care for Calypso drives much of his personal arc.
- Calypso – Formerly trapped on the island of Ogygia, Calypso is now mortal and struggling to adapt. Her sharp tongue and growing sense of vulnerability highlight her inner conflict as she learns to fight, heal, and love in a world that constantly demands more of her.
- Meg McCaffrey – A demigod daughter of Demeter and Apollo’s unpredictable “master,” Meg is torn between her loyalty to Apollo and her manipulation by her cruel stepfather, Emperor Nero. Her emotional depth and internal battles add complexity to her relationship with Apollo.
- Josephine and Emmie – A former pair of Hunters of Artemis and caretakers of the magical Waystation, these characters offer sanctuary and wisdom. Emmie, formerly known as Hemithea, was once granted immortality by Apollo. Their backstory enriches the narrative with themes of love, sacrifice, and mortality.
- Agamethus – A silent ghost and brother to the prophet Trophonius, Agamethus becomes an unlikely guide to Apollo. His tragic, wordless assistance evokes the importance of unspoken loyalty and familial bonds.
Theme
- Redemption and Responsibility – Central to Apollo’s arc is the idea that power alone does not grant virtue. As he witnesses the consequences of his past choices, he begins to grasp the weight of true heroism and responsibility—a recurring thread as he strives to right his wrongs.
- Mortality and Vulnerability – Apollo’s forced humanity strips him of divine privilege, laying bare his physical and emotional limitations. The pain of losing immortality drives a profound narrative exploration of fear, empathy, and growth.
- Identity and Transformation – Across the story, many characters—Apollo, Calypso, Leo, even Meg—grapple with shifting identities. Whether through loss, love, or pain, each is forced to redefine themselves in the face of trials that demand reinvention.
- Friendship and Loyalty – The makeshift family of Apollo, Leo, and Calypso, as well as the community within the Waystation, underlines the importance of chosen kin. Bonds are forged not by blood or fate, but by the willingness to fight and sacrifice for one another.
- Prophecy and Fate – The looming “Dark Prophecy” drives the action and infuses tension throughout. The motif of visions and oracles questions the balance between destiny and free will, especially for a god once in control of the future.
Writing Style and Tone
Rick Riordan’s signature first-person narration, laced with fast-paced humor, biting sarcasm, and modern references, is once again the hallmark of The Dark Prophecy. Apollo’s voice is both regal and ridiculous—a grandiose self-image constantly undercut by his mortal struggles. The narrative tone fluctuates between slapstick comedy and introspective seriousness, giving the story an emotional duality that resonates across age groups.
Riordan excels in juxtaposing mythological grandeur with contemporary absurdity—where gods lament acne and ancient beasts hide beneath Midwestern cities. His prose is crisp and cinematic, filled with witty dialogue, imaginative settings, and rich mythological allusions. Flashbacks are seamlessly interwoven, revealing poignant backstory without slowing momentum. The tone often satirizes divinity and power, but beneath the jokes lies a sincere meditation on loss, healing, and the journey toward becoming better—not just greater.
