What does it mean to say "I love you"? Ariadne is a single, forty-something writer and mother embroiled in an affair with a married man. At the core of her current work, a manuscript about the declaration of love, is the need to understand why: why her lover has returned to his wife, why their relationship still lingers in her mind, why she's unable to conquer her longing. Lacking answers and struggling financially, she joins a research study in which she's paid to live with an AI device called Dirk. But the study quickly enters unchartered territory. Capable of mapping Ariadne's brain--and to some extent reading her mind--the AI calls into question issues of both privacy and consciousness: how we communicate our thoughts to others, what it means to embody our desires, and whether we ought to act on them. I Can't Get You Out of My Mind asks what it means to be human--to be physical creatures endowed with a conscious mind, aware of our finitude--and to love.
