Ariana Elowin has one rule: keep life neat, organized, and far away from chaos. Unfortunately, chaos has a name. And that name is Theo Reyes. Ariana is a straight‑A, planner‑obsessed goodie two‑shoes who's never missed a homework assignment. Theo is the school prankster, the class clown, the reason teachers sigh before taking attendance. They've never agreed on anything-except that they can't stand each other. So when their teacher pairs them for a month‑long group project worth 40% of their grade, Ariana is convinced the universe is personally attacking her. Theo thinks it's hilarious. Forced into late‑night study sessions, chaotic arguments, sabotaged slides, spilled iced coffee, and a growing list of "rules" Ariana makes just to survive him, the two opposites start to realize something terrifying: They might not hate each other as much as they thought. And that's when things get complicated. Because enemies are easy. Partners are hard. But falling for the one person who drives you insane? That's impossible... right?

When Thalia Grace crash‑lands back at Camp Half‑Blood after a mission gone sideways, she expects monsters, drama, and maybe a lightning‑induced migraine. What she doesn't expect is landing directly on top of Nico di Angelo - who was very much minding his own business, thank you. Somehow, the two most emotionally constipated children of the Big Three get stuck together on a quest that absolutely no one thinks is a good idea. Camp panics. The gods panic. The Stolls start taking bets. And through storms, shadows, bickering, and a prophecy that definitely should've been proofread, Thalia and Nico discover that maybe the only thing more dangerous than monsters... is caring about someone who understands the darkness in you.
