What if it wasn't an accident?
1969. Eloise Shepherd, one of MI6โs brightest rising stars, is working undercover in Soviet Russia as Magdalina Novikova. Her mission is to persuade nuclear physicist Stanislav Kalashnik to defect and bring his knowledge of Russian weapons back to the UK. On the verge of success, the operation fails suddenly and spectacularly.
17 years later, Kalashnik is Chief Engineer at the power plant near Pripyat known as Chernobyl. His concerns for the safety of the plant are growing. When his views lead to accusations that question his patriotism, he finds himself in a very risky position.
Meanwhile, back in London, Eloise Shepherdโs life and career are spinning out of control when sheโs approached with a one-time offer to redeem herself. The mission: to get Kalashnik over Soviet borders once more. Itโs an opportunity that could change everything and Eloise knows thereโs no reward without risk. But sheโs heading straight towards a danger far greater than she could ever have anticipated.
