Fire Guardian Olivia Fénix is pushed into a volunteer teaching post at Camp Elementis Horizon, a remote summer training site on the Isle of Portland. Her family hopes teaching younger students will offer her a reset.

Her students' abilities are becoming increasingly erratic under the Council's rigid teaching methods. Olivia's unconventional approach could be the answer, but the Council may not allow it.

When mysterious disturbances in the energy pathways trigger sudden, synchronised surges across the camp, Olivia begins to suspect the children in her care are being deliberately targeted. To protect them, she must navigate Council politics before the summer becomes something none of them survive.
