A secret hidden in our genetic code will rewrite history as we know it...

Sara Morin, a brilliant computational biologist, makes a discovery that will fundamentally change our understanding of human evolution. But when she publishes her results, she ignites a firestorm she never expected.

Hunted by a ruthless assassin, Sara finds herself partnered with New York Times reporter Marcus Byron. Together they race across Europe, through Cathar castles, Aegean islands, and beyond. On the run, Sara must decipher a mysterious set of genome sequences.

As they begin to uncover answers, powerful forces turn their sights on Sara. If she can't decode the sequences in time, she'll end up dead-and the world will never know the shocking truth about the people who rule it.
