History Literature / TheHeroesOfOlympus

** Leo, in addition to his technological talent, has [[spoiler: fire powers]]. Great for fighting monsters, right? Yeah, except for the fact that [[spoiler: said powers are difficult to control and extremely dangerous. Just ask Leo's mom. Oh, wait, you can't: she died in a fire ''started by accident by her son''.]] And Apparently the last son of Hephaestus with the ability [[spoiler: started the Great Fire of London.]] So that should give you an idea of what we're dealing with here.

** Subverted with Leo, Frank, and Hazel, since Leo doesn't act on any feelings he has for Hazel, and Hazel isn't in love with Leo but rather with Frank. However, who is the Betty and who is the Veronica is more clear cut in this case. Frank is the Betty, since he and Hazel are best friends, he houses feelings for her, and he lacks self-confidence, while Leo is the Veronica, since he interferes in and complicates Hazel and Frank's relationship and is far more assured of himself than Frank is. By ''The House of Hades'', this triangle is effectively over, since [[spoiler: Leo has fallen in love with Calypso.]]. All three of the characters comment on this new development.

** Not during a fight like most boasts, but this still deserves mention. When Hazel, youngest of the heroes, makes this declaration to Hecate, goddess of magic and crossroads: "We’re going to find a way to stop Gaea. We’re going to [[spoiler: rescue out friends from Tartarus.]] We’re going to keep the crew and ship together, and we’re going to stop Camp Jupiter and Camp Half-Blood from going to war. We’re going to do it all." Hecate, for her part, is interested to see if Hazel and the others can actually do it, claiming it would be magic worth seeing.

** Percy in [[''The House of Hades'']] to the [[''empousai'']]: "You mix Greek and Roman, and you know what you get? You get [[SuddenlyShouting BAM!]]"

** Jason returns after seemingly being [[YouCannotGraspTheTrueForm god-fried]] ''The Lost Hero'', though the narration doesn't make it clear whether he was really dead or not.

** A lot of people, Greek and Roman,did ''not'' feel bad when [[spoiler: Octavian got himself launched by a flaming catapult and died. Not even his most loyal bodyguard bothered to warn him that his toga was snagged.]]

The first book, ''The Lost Hero'', introduces a new half-blood named Jason who finding himself in a school bus with absolutely no memory of who or what he is, along with a girl, Piper, and a boy, Leo. The three turn out to be half-bloods and run into Annabeth (from the first series) and someone named Butch, who are looking for the missing Percy Jackson. Jason, Piper, and Leo are sent on a quest to free the captured Hera and end up realizing their destinies are far greater than they ever imagined. Meanwhile, Gaea the Earth Mother is stirring and reveals her plan to take down the gods, who are in no condition to fight her due to their warring Greek and Roman aspects.

** By the end, most of the characters are in a relationship for have some sort of ShipTease with someone else (even Tyson and Ella!) except for Reyna.

** Jason as the [[WhiteMaleLead quest leader]], Piper as the Native-American love interest and Leo as the [[BlackBestFriend Latino Best Friend]].

* AmbiguouslyHuman: In the first book, Procrustes ''looks'' human, but can be killed by a celestial bronze sword. He's also too old to be a half-blood, leaving it unclear as to what he really is.

** Hazel is revealed to be this at the end of her flashbacks, thus proving that once again Hades/Pluto is really the only god of the Big Three who is able to make a vow and actually ''make good'' of it (though her narration about things, like UsefulNotes/WorldWarII, foreshadows the fact that she is from the forties.

* RomanticPlotTumor: Though your mileage may vary with the LoveTriangle and the LoveDodecahedron, fans almost universally hate Jason and Piper's relationship, as they mostly got together because they were the male and female leads (sans Leo) and had fake memories of being in a relationship. So their romantic interactions can really feel like this. [[spoiler: Rick practically admits how awful their relationship was by making them break up in TrialsOfApollo. They didn't even do it onscreen.]]

* EveryoneMustBePaired: In ''Literature/PercyJacksonAndTheOlympians'', only OfficialCouple Percy/Annabeth gets any focus, with a couple minor side pairings like Grover/Juniper and Clarisse/Chris that are few and far between. Come the sequel series ''Literature/TheHeroesOfOlympus'', and suddenly romance plays an important role in the plotlines of every single major character, and Percy/Annabeth is joined by Jason/Piper, Hazel/Frank, Leo/[[spoiler:Calypso]], and Nico/[[spoiler:Will Solace]]. The only main character who doesn't end up with anyone is Reyna, who plays the RomanticRunnerUp.

** Bryce Lawrence, a Legacy of Orcus (got of punishment in the Underworld) and an exile from Camp Jupiter (recently reinstated by Octavian), tries to take on Nico and Reyna - two experienced demigods, a son of Hades and daughter of Bellona the war goddess, respectively - in ''The Blood of Olympus''. An enraged Nico deals with him in one blow by unleashing a single "flood of pain and anger", turning him into a mindless ghost and sending him to the underworld.

* FiveTokenBand: The seven demigods of the prophecy include a Native American girl (Piper), a Latino boy (Leo), a Chinese-Canadian boy (Frank), a black girl (Hazel), and two white guys and a girl (Jason, Percy and Annabeth).

Doubles as AffirmativeActionLegacy, as the first series was much whiter and only had one female main character.
