The Covenant of Genesis (Wilde/Chase 4‪)‬

In the brilliant fourth book from Andy McDermott, Nina Wilde must battle the Covenant of Genesis if she is to find the world's greatest archaeological treasure...
Off the coast of Indonesia, archaeologist Nina Wilde makes an explosive find: evidence of a settlement that existed over a hundred thousand years before any previously known civilisation. But when her ship is attacked, it becomes clear that the clandestine religious group calling itself the Covenant of Genesis will stop at nothing to prevent her from revealing this knowledge.
With her fiancé Eddie Chase, Nina embarks upon a dangerous worldwide search to expose the Covenant of Genesis - and the incredible secret they will kill to conceal.
