Pearl longed for the life of a normal American teenager: summers at the pool, friends, backyard barbecues in the Washington DC suburbs.But she was different.

And it's only now, at nineteen years old, that she has started to understand what role she is to play.What her parents intend for her. For Pearl Tao, any hope of escape lies with two British spies: Trish Patterson, sidelined in disgrace, and Philip Mangan, blown and discredited - and following his own trail of corruption.Finding out the truth about Pearl will be the most urgent, the most dangerous mission they'll ever undertake.
