On the shadowed slopes of Mt. Makiling, something ancient awakens. Eight high school seniors thought their final trip together would be just that—a farewell adventure. Instead, they’re marked by the diwata of the mountain, chosen to fight a war they never knew existed. To claim their powers, they must survive beasts from Filipino trickster Tiyanak, mind-warping Tikbalang, and the monstrous Kapre lurking in the trees. They return changed. Hunted. The Berbalang—a nightmare cloaked in human skin—has sensed their power. And it wants it. Their graduation will not be a celebration. It will be a massacre. They are no longer students. They are The Makiling Guardians.
