The Heart Principle

Violinist Anna Sun went viral with one performance and has been paralyzed by burnout ever since, unable to recapture that moment. When her longtime boyfriend asks for an open relationship before committing, a hurt Anna decides to try one-night stands of her own, and the most unsuitable man she can find turns out to be tattooed, motorcycle-riding Quan Diep, who is quietly rebuilding his life after cancer. What starts as casual becomes something far deeper because Quan accepts Anna exactly as she is, just as she is beginning to understand herself and to suspect she is autistic. Then a family crisis pushes her into a caregiving role that threatens to crush her. Tender and emotionally heavy, the third Kiss Quotient-world novel explores burnout, neurodivergence and family duty alongside its love story.
