The thrilling third novel from multi-award-nominated author Adam Brookes is paranoid, tense spy fiction at its very finest. 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. Her gift for mathematics means overprotective parents and college sponsorship from a secretive technology corporation. And now, aged nineteen, she is beginning to understand what her parents intend for her. The terrifying role she is to play. Her only hope of escape lies with two sidelined and discredited spies: Trish Patterson and Philip Mangan. Finding out the truth about Pearl will be the biggest mission they'll ever undertake. "Authentic, taut and compelling. Brookes is the real deal." -- Charles Cumming
