THE UNCHARTED INTERVAL

An island that should not exist. Evidence from decades that should never overlap. And a scientist drawn toward a past she thought she had already buried.

When an expedition discovers a nameless island in a remote stretch of the Pacific, geophysicist Dr. Tessa Rourke believes she may have found the discovery of a lifetime.

Then a violent storm cuts the team off from the outside world.

What they find ashore makes no sense: a military boat from the 1940s, an abandoned research camp from the 1990s, ancient stone ruins, and radio transmissions that seem to originate from entirely different decades.

The deeper they move into the island, the stranger the evidence becomes.

Equipment fails. Memories begin to feel unreliable. Suspicion spreads through the stranded team. And somewhere inside the static, Tessa hears a voice she recognizes.

A voice connected to an event from her own past.

As the expedition pushes toward the island's mysterious interior, Tessa must determine whether the impossible clues around them point to a distortion of time, an unknown natural phenomenon, or something even more unsettling.

Because Thessos is not simply hiding what happened there.

It may be exposing what Tessa has spent years trying not to remember.

THE UNCHARTED INTERVAL is a science-fiction survival thriller about isolation, impossible evidence, buried memory, and a remote island whose deepest mystery may have nothing to do with time at all.
