Hypoxia
HYPOXIA a novel by Matt Heart
A reunion was supposed to bring them back together. Instead, it might bury them forever.
Fifteen years after graduation, Amber arranges an exclusive untraditional high school reunion on a remote luxury island off the coast of Maui. The resort is private, the guest list tight, and the drinks never stop flowing. Old flames rekindle, secrets resurface, and for a moment, it feels like paradise.
But beneath the waves, a violent shift brews. A volcanic eruption deep in the Pacific triggers a colossal tsunami—and within minutes, paradise turns into a watery hell.
The island is swallowed. The resort is crushed. And the survivors—trapped in the remains of a once-glamorous high-rise—are forced into the darkness below, where the air is thin, the water is rising, and predators are circling. Some find refuge in a submerged elevator shaft, others in the twisted wreckage of the spa. But one thing becomes the only way out is through.
As panic sets in and betrayals rise to the surface, the line between humanity and survival begins to erode. Because the ocean doesn't care who you were. Only who you'll become… when the air runs out.
