Peace was our favourite illusion... Jacinthe Trevion's only goal in life is to prove that she is not a criminal like her father, while Mazarine Stallard's is to become the perfect daughter following the footsteps of her father, the Commanding Inquisitor of Telluria. For five centuries thrived the city of Telluria, the last pocket of modern civilization to survive underground after the Fall of Mankind. When a series of strange events disrupt the city's routine, it falls on Jace and Mazarine's shoulders to uncover the conspiracy that spans centuries in the making. They are two daughters, fighting for different reasons but wanting the same goals, and eventually realising that they have more in common than they care to admit. And when death threatens to take one of them, they learn to fight back. Already miles beneath the ground, Jace and Mazarine must find a way to keep themselves from being buried alive.
