A tragic massacre awaits the Bronze Age of Astryss. Mistletoe is a dryad, protecting the sacred tree that makes her home a paradise. When an ancient blight threatens all life in the canyon, she sets out to banish it forever. Things escalate when a group of outsiders enter her territory, and as their actions endanger the land further, Mistletoe must defend what she loves at all costs. Especially by taking matters-and a soon-to-be-bloody axe-into her own hands. Meanwhile, six students from the Academy of Oraklos in Ellathen are attending a class field trip. When a detour leads them into a lush canyon, they face interpersonal issues and the woes of adolescence, all while confined by walls of rock. However, they soon discover that they are not alone, that something dangerous lurks to protect the forest. And when night falls, they learn they are being hunted.
