Tartarus: the darkest pit in the underworld and the deepest recess of the unconscious. The abyss where the gods threw away their dirtiest secrets to be forgotten. But nothing could bury her guilt … nor her curiosity. When Percy finally died, everyone knew he tried for rebirth. Yet Artemis recognized a soul sentenced to eternal damnation.

An eternal guardian maintains a fluctuating world of night and poison. He doesn't get many visitors. But the moon has risen. Percy isn't happy that she's back.

Grand secrets are tools to be wielded, weapons and blackmail. But small secrets are shared intimacies—bonds that bridge worlds. Secrets destroy … but they also build. And a proper Slytherin does both.
