Something was hidden inside a box of bones.
Something was coded into a love song.
Together, the messages pointed archaeologist Katie Catton and her husband, Leo, toward the Dari n jungle-and an ancient geometric mystery linking G bekli Tepe to a place no map admitted existed.
Katie and Leo followed the trail. Then the world began to change.
People everywhere started losing their sight-not into darkness, but into a false reality where crucial things simply vanished.
Katie's mother recognized an alteration of human perception unlike anything known to biology. Leo's mother recognized something else: evidence of a hidden knowledge older than recorded history.
It was waiting in the Colombian jungle.
The two women crossed an ocean to pull their children out of a place guarded by something that had been shaping human understanding for millennia.
Katie and Leo had not sought this discovery.
It had sought them.
Now, one of them might already be The Colombian Specimen.
