The Salt and the Shadow They survived the Pit, but they didn’t leave it behind. After falling into Tartarus together, Percy and his younger sister, Emily, returned to the surface with a bond that terrified the gods—a codependency forged in hellfire and blood. Following a forced year of separation intended to "heal" their obsessive attachment, Emily returns to Camp Half-Blood. But the distance didn't fix them; it only proved that the rest of the world is white noise. In a camp full of heroes, the Jackson siblings are a storm of trauma and protective rage that no one—not even the gods—can weather.
