The Spy's Daughter by Adam Brookes
MEET PEARL TAO: AN AMERICAN GIRL WITH A LETHAL SECRET
Pearl longs for the life of a normal American teenager: summers at the pool, friends, backyard barbecues in the Washington DC suburbs.
But she is different.
Pearl has a gift for mathematics, a college sponsorship from a secretive technology corporation, and a family riven with anger and dysfunction.
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 the truth of Pearl Tao will be the most urgent, the most dangerous mission they'll ever undertake.
