Showing The Ark by Boyd Morrison

Also published as THE ARK.

Dilara Kenner, an ambitious young archaeologist, must run for her life when an old friend is murdered right in front of her. Before he dies in her arms, he gasps a few cryptic words about a vast conspiracy to hide an awesome historical artifact and tells Dilara that the only person who can help her is a former Army combat engineer named Tyler Locke.

Dilara finds Locke on a North Atlantic oil platform but the helicopter she arrives in suffers a mechanical failure and goes down next to the rig. The quick-thinking Locke manages to rescue everyone on board, including Dilara. She tells him that the helicopter crash was no accident. Someone wants to stop her from finding Noah's Ark.

Locke and Dilara head to Arizona, and their investigation reveals a chilling discovery. A group of religious fanatics has recovered a weapon from the Ark that will let them recreate the effects of the biblical flood and mold the remnants of humanity according to their leader's twisted vision. Now Locke and Dilara have just seven days to find the Ark and the secret hidden inside before it is used to wipe out civilization again...
