Normal days weren't common for the kids at Camp Half-Blood, so when three demigods get sucked into a whirlwind of prophecies and ancient gods, it's hard to stay sane enough to complete the quest. Daughter of Hemera, daughter of Nyx, and son of Athena must band together and unravel the mystery of Obsidians Keep.
Legends whisper that the maze traps all who dare to enter, with shifting walls and twisting corridors, along with a few long forgotten ancient animals. They say it's worth the risk when what lies in the center, a key to unlocking a power long forgotten- one that could awaken the Ancient gods themselves, yet many have been lost to the madness of the maze.
The gatekeeper of the maze warns only one may enter the maze without consequence, but when all three demigods cross the threshold, the stakes spiral into a living nightmare.
As the labyrinth begins to test their minds, hearts, and trust in each other and others, the trio must navigate not only the dangers in the hollow halls, but also the secrets and betrayals that could tear them apart. In Obsidians Keep, survival isn't just about escaping- t's about staying sane long enough to make it out alive.
Some doors should never be opened. Some prophecies should never be fulfilled.
