The Book of Names by Jill Gregory & Karen Tintori

As a result of a childhood tragedy, Professor David Shepherd finds himself the keeper of knowledge that holds the world in a delicate balance. He knows who is in the Book of Names, an ancient text originating with the biblical Adam, thought lost forever. By Kabbakustic tradition, the book contains the names of each generation's 36 righteous souls - the Hidden Ones - by whose existence alone the world survives. Legend holds that if all 36 Hidden Ones were eliminated, the world would be destroyed.

The Hidden Ones start dying, and the world grows increasingly unstable, massive flooding in New York, brutal terrorist attacks in Melnourne. David finds himself battling against the secret religious sect the Gnoseos and his involvement turns personal when one of the names turns out to be that of his own step-daughter.

With the help of an Israeli ancient texts researcher, David races to decipher the traditions of the Kabbalah to save the remaining righteous souls, his daughter ... and the world.
