A riveting psychological drama that challenges the way we understand others—and our own sense of self

Mia is a schoolteacher in Denmark. Her husband, Frederik, is the charismatic headmaster of a local private school. During a vacation on Majorca, they discover that a brain tumor has started to change Frederik's personality. As it becomes harder and harder for Mia to recognize him, she must protect herself and their teenage son from the strange, blunted being who now inhabits her husband's body—and with whom she must share her home, her son, and her bed.

When millions of crowns go missing at the private school, Frederik is the obvious culprit, and Mia's private crisis quickly draws in the entire community. Frederick's new indifference and lack of inhibition rupture long-standing friendships, isolating Mia and making her question who Frederik really is. Was the tumor already affecting him during the years they had been so happy together? And does it excuse Frederik from fraud?

Mia enlists the help of a lawyer named Bernhard, whom she meets in a support group for spouses of people with brain injuries. As they prepare Frederik's defense, the two of them wrestle with the latest brain research, the age-old question of free will—and their growing attraction to each other.

Jungersen's lithe prose and unexpected plot twists will keep readers hooked until the very last page.
