You Disappear

Mia’s happy marriage is shattered when a brain tumor begins to change her husband’s personality beyond recognition. As Frederik becomes ever more a stranger before her eyes, the revelation that he has used his position as headmaster to mbezzle millions from his school's treasury turns Mia's private crisis into one that involves the community. But this disgraceful crime could become Mia’s salvation: working with a defense lawyer to build Frederik's case, they wrestle with the latest brain research, the question of free will—and their growing attraction to each other.
 
Consumed by her new obsessions, Mia must reexamine everything she thought she knew about her marriage, and herself, as she too starts to change. . . .
