Extinction - Chris Liberty

Gracen and her friends escaped the volcano.

But they did not escape the nightmare. And as they would soon discover, survival was just the beginning.

When Gracen and her friends crash into the sea and swim ashore on Ilha Bela, the island looks like safety-green, quiet, untouched.

It isn't.

Dinosaurs stalk the jungle in greater numbers than on Ilha da Morte, the last remnants of Project Timeline still exist here, and someone Gracen left for dead has returned.

But the greatest threat doesn't come from the jungle. It comes from a betrayal that fractures the group.

Gracen is forced to confront the horrifying possibility she has feared since she first started her journey: if the past is disturbed, the present may not survive it.

In this explosive conclusion to the Project Timeline saga, loyalty is tested, time fractures, and survival comes at a devastating cost.
