After Diana thwarts a stunning attempt to defeat the Amazons and Themyscira for good, she has finally been granted permission to start training as a warrior! Except, the goddess Artemis brings news that children all over are disappearing without a trace. Diana is the only one who can be trusted to save them--even if she must confront Hades, Persephone, and all of the undead souls and mythical creatures of the Underworld. That is, until she discovers that a far more sinister villain is out to capture her--and will do whatever it takes to find her. With her warrior training barely underway, will young Wonder Woman be able to rely on her strength from within to save the missing children and defeat Hades? Or will she instead be dragged to the Underworld--forever?
