Commander Constance 'Bucky' Powers is Scotland Yard's top operative. As lethal as she is beautiful.

Bucky uncovers a plot by the man known only as Zen to replace the world's most influential people with replicants that are under his control.

She begins to unravel the puzzle that sends her weaving through a labyrinth of locales from Soho to La Paz, Mexico to New York to save who she believes will be Zen's next victim. Prince William of England.

This mission will require all of her special skills.
