The Son of Neptune
The Son of Neptune is the second installment in Rick Riordan's popular 'The Heroes of Olympus' series, a fantasy action-adventure novel deeply rooted in Greco-Roman mythology. It follows Percy Jackson, a demigod who awakens with amnesia and finds himself at Camp Jupiter, a training ground for Roman demigods. Joined by new companions Frank Zhang and Hazel Levesque, Percy embarks on a perilous quest to Alaska to free the God of Death, Thanatos, and combat the rising threat of the primordial goddess Gaea and her monstrous offspring. Targeted at a middle-grade to young adult audience, typically ages 9-12 and up, the book is characterized by its fast-paced plot, humorous dialogue, and integration of classical myths into a modern setting. While the narrative involves frequent battles and intense situations, it maintains an adventurous tone, encouraging themes of heroism, friendship, and self-discovery.
Concerns
Violence
HighThe book contains frequent and intense depictions of combat between demigods and mythological monsters and giants. Battles are often detailed, involving weapons, magical abilities, and the implied or explicit defeat and dissolution of various creatures. Characters are regularly in life-threatening situations and sustain injuries.
Percy Jackson repeatedly engages in physical combat, such as strangling a sea monster in the Carquinez Strait and constantly battling immortal Gorgons who reform after being defeated. The climax features a large-scale battle where Percy, Frank, and Hazel confront the giant Polybotes and his army. Percy is described as stabbing Polybotes multiple times, culminating in the giant dissolving into ash after a god's intervention.
Witchcraft & Occult
HighThe entire narrative is fundamentally built upon Greek and Roman mythology, involving polytheistic gods, goddesses, demigods, mythical creatures, and inherent magical abilities. Characters regularly use supernatural powers, engage in divine quests, interact with prophecies, and encounter various forms of magic and occult practices as central elements of the plot.
Hazel Levesque possesses the power to summon precious gems and metals from the earth, an ability tied to a curse from her past and her divine parentage as a daughter of Pluto. The central quest requires the demigods to travel to the land beyond the gods to free Thanatos, the God of Death, whose imprisonment has led to unkillable monsters and a disruption of the natural order.
Scary & Intense Content
HighThe book features a consistently high level of scary and intense content, including frequent encounters with dangerous and often gruesome mythological monsters. The characters face constant peril, engage in life-or-death battles, and deal with the high stakes of a prophecy that threatens the world. Descriptions of monsters and combat can be vivid and suspenseful.
Percy Jackson is continuously pursued by two immortal Gorgons, Stheno and Euryale, who regenerate after being defeated, creating persistent psychological and physical danger for him throughout the initial chapters. The overarching plot revolves around the imminent attack on Camp Jupiter and the need to free Thanatos, the God of Death, to prevent Gaea's forces from becoming truly immortal, placing the characters in numerous perilous, world-threatening situations.
Anti-Christian Themes
HighThe fundamental premise of 'The Son of Neptune,' and the entire 'Heroes of Olympus' series, is rooted in Greco-Roman polytheistic mythology. The narrative centers on a world where a pantheon of gods, goddesses, and demigods are active and central to the universe's functioning. This inherent polytheistic worldview, while not directly mocking or criticizing Christianity, presents a religious framework that stands in direct opposition to Christian monotheistic beliefs.
The protagonists are all demigods, children of various pagan deities like Neptune (Poseidon), Pluto (Hades), and Mars (Ares), and their quests are driven by the will and prophecies of these gods. Divine figures such as Mars appear directly to the demigods, delivering prophecies and instructions for their quests, thereby establishing a polytheistic spiritual system as the primary truth within the story's universe.
LGBTQ & Gender Identity
MediumWhile 'The Son of Neptune' itself does not explicitly feature LGBTQ+ themes or characters, a prominent character introduced in this book, Nico di Angelo, is later revealed to be gay in a subsequent novel within the same 'Heroes of Olympus' series. The author, Rick Riordan, has made a conscious effort to include diverse LGBTQ+ representation in later books and series, indicating an evolving presence of these themes across his broader literary universe.
Nico di Angelo, a son of Hades, makes an appearance in 'The Son of Neptune' as a mysterious figure from Percy's past, though his romantic feelings for Percy Jackson and his identity as gay are not explicitly revealed until 'The House of Hades,' the fourth book in the series. The broader Riordanverse, including later series like 'Magnus Chase and the Gods of Asgard,' explicitly features genderfluid characters like Alex Fierro, demonstrating the author's intentional inclusion of gender identity themes for young readers.
Romance and Sexual Content
MediumRomantic subplots are present and are generally innocent, involving crushes and mild physical affection appropriate for a middle-grade audience. Kissing is limited to the cheek or brief mentions of past romantic gestures. There is a vague, disturbing reference by a fan about 'sex slaves' in the Amazon society, though the book's portrayal frames it as subservient gender roles for men rather than explicit sexual slavery.
Hazel Levesque and Frank Zhang develop a romantic connection throughout the quest, culminating in their first kiss after a significant battle, and Frank later entrusts Hazel with his life-tethered piece of wood. Percy Jackson experiences fragmented memories of his girlfriend, Annabeth Chase, specifically recalling her habit of kissing him when he did something 'stupid,' indicating their established romantic relationship.
Profanity
MediumThe book contains minimal explicit profanity. The language used is generally mild, with occasional instances of words like 'ass' mentioned. Stronger language is typically implied through context, such as characters' reactions to what animals are 'saying,' or through translated foreign curses.
Arion, a magical horse, is frequently characterized by Percy Jackson as having a 'potty mouth' and 'cussing,' though his exact words are understood by Percy but not explicitly stated in English for the reader. Hazel Levesque is noted to curse in Latin during moments of frustration, using insults like 'son of a gorgon' and other strong suggestions against characters like Octavian, which are understood by Percy as offensive.
Disrespect & Rebellion
MediumCharacters, particularly demigods, frequently exhibit disrespect or defiance towards authority figures, including gods and human superiors. This is often portrayed humorously, sarcastically, or as justifiable rebellion against oppressive or misguided leadership, and is a recurring element of the series' character dynamics.
Percy Jackson often displays a sarcastic and irreverent attitude when interacting with divine figures, such as making lighthearted comments even during serious conversations with the Roman god Mars. Octavian, the camp's augur, is portrayed as power-hungry and manipulative, leading the protagonists to frequently question and defy his authority and schemes.
Substance Use
LowThere is no direct depiction of substance use by the main characters within 'The Son of Neptune.' Historical context from the previous 'Percy Jackson and the Olympians' series mentions Percy's abusive stepfather, Gabe Ugliano, who smoked, drank, and gambled. However, this is background information and not central to the plot or character actions in the current book.
No specific instances of alcohol, drug, or smoking by main characters or directly depicted within the narrative of 'The Son of Neptune' were found. The book consistently maintains content appropriate for its middle-grade to young adult audience. While not occurring in 'The Son of Neptune' directly, Percy Jackson's former abusive stepfather, Gabe Ugliano, in the prior series, was characterized by his smoking, drinking, and gambling habits.
Other Notes
Target Demographic
Ages 10-14. This recommendation is based on the book's Lexile level (640L) which is suitable for average 8-11 year olds, combined with its frequent depictions of intense mythological violence, peril, and complex thematic elements such as fate, sacrifice, and burgeoning romantic relationships. The Heroes of Olympus series, of which this is the second book, also introduces evolving themes of identity and diversity in later installments, requiring a slightly higher maturity level for full comprehension.
Additional Notes
The 'Heroes of Olympus' series builds upon the previous 'Percy Jackson & the Olympians' series, assuming prior knowledge of Greek mythology and its characters. While 'The Son of Neptune' reintroduces Percy Jackson, new readers might benefit from understanding the broader world-building. The inclusion of LGBTQ+ themes becomes more explicit in later books of the series and subsequent Riordanverse installments, which parents should be aware of if their children continue reading the author's works. The series consistently promotes positive themes of friendship, courage, and teamwork.
