Amazon.com Book Description (ISBN 0380730073, Mass Market Paperback)

There is nothing unusual about Jared Baker -- until a sudden, tragic accident sets something inside of him free. With the destruction of everything he loves comes the birth of terrifying and irresistible impulses, as two hidden selves arise out of the darkest corners of his personality, each one as volatile as dynamite ... and twice as deadly.

Behavioral scientist Marcus Sonnenberg knows what has happened to Jared Baker. Under the guise of aid, he intends to bend Jared to his will, to use the newborn "gifts" of a confused, frightened man for Sonnenberg's own ends. But there are other powerful covert forces determined to get their hands on this devastating human "weapon." And now Jared Baker must run for his life from organized criminals, government assassins ... and from what he, himself, has become.
