One-year-old Mia is just a tiny human baby surrounded by giant Titans! After being rescued by Mara, the fierce leader of Titan Valley, Mia calls her "Mom" just to save herself. But to her surprise, Mara takes it seriously, and three powerful Titan siblings begin treating her like their precious little sister!
Desperate to escape and find her human home, Mia tries every trick imaginable. But everything changes when her tiny hand turns the sacred Heartstone completely black, revealing her identity as an Echo-Born—a rare human capable of foreseeing disasters and hearing the voices of the dead.
As the Titan Heart weakens and mysterious deaths spread fear across the valley, Mia is blamed for an ancient prophecy of destruction. With a ruthless elder secretly plotting to seize ultimate power, the smallest member of the family may be their only hope.
Now, the baby who once did everything she could to escape must fight to save the family that never stopped loving her. Because true family isn't defined by blood or species—it's defined by love and the choice to stay.
