The stunning novel about our fiercest loyalties, deepest desires and the power of forgiveness

Rosalind Porter's biggest mistake was love . . . Chicago, 1950. Before Thomas Weaver broke her heart and wrecked her career, Rosalind was a leading atomic researcher. Five years on, she's alone and can barely make ends meet. Which is when Thomas - a shattered man - walks back into her life, begging forgiveness.

Rosalind would, and should, say no but for two reasons. First, she still loves Thomas. And, second, Charlie Szydlo. Charlie's a damaged FBI agent who believes Thomas is spying for Russia. He wants Rosalind to find evidence. But this is a dangerous game. Who can she trust? Thomas, who taught her how to love? Or Charlie, whose pain she yearns to heal?
