Can she both succeed and survive as a woman in a man’s world? The intricate threads of the story draw together a group of diverse characters in London and Spain whose lives come together in an explosive conclusion as Verity becomes the target for sabotage and final betrayal in a battle whose outcome is far from predictable.
