The main plot revolves around two separate groups of demigods attempting to reach the Doors of Death in the House of Hades, a perilous Underworld labyrinth.

One group, comprising Percy Jackson, Annabeth Chase, and Bob, travels through the Underworld, facing trials and tribulations designed to test their strength, loyalty, and resilience. They navigate treacherous landscapes, confront mythical creatures, and encounter various spirits and gods, including the chilling goddess Hecate and the enigmatic Thanatos. Their journey is fraught with danger, highlighting the themes of sacrifice, courage, and the importance of friendship in the face of overwhelming odds. Annabeth's growing connection with the power of Athena's wisdom becomes crucial.

The other group, consisting of Jason Grace, Piper McLean, Leo Valdez, Frank Zhang, and Hazel Levesque, is tasked with navigating the treacherous labyrinth of the House of Hades itself. Their journey is marked by internal conflict and the increasing weight of their responsibilities. Leo's engineering skills prove vital, while Frank's strength and Hazel's connection to the Underworld become crucial to their survival. Piper's charmspeaking skills are tested as they face betrayal and manipulation within the labyrinth itself. Jason's struggle with his identity and leadership skills is a central theme, further emphasizing the burden of responsibility and the challenges of teamwork under pressure.

Both teams eventually converge at the Doors of Death, but not without significant losses and betrayals. The overarching theme of hope versus despair is powerfully explored, as the demigods confront their own mortality and the potential annihilation of their world. The book dramatically raises the stakes, underscoring the monumental task facing the seven demigods in stopping Gaea, the Earth Mother, from unleashing chaos upon the world.

The emotional toll of the journey leaves its mark on each character, reinforcing the themes of loss, sacrifice, and the enduring power of love and loyalty. Ultimately, the book ends with a significant cliffhanger, leaving the fate of the demigods hanging in the balance as they struggle to reach their goal before Gaea's forces gain the upper hand.
