From the author of the international bestselling debut novel, Agatha The author works part time as a psychologist and part time as a writer. Her background in psychology makes Blue Notes a well-researched and realistic read, even though she invented the grief pill 'Callocain,' which is featured in the book. Blue Notes explores the following main themes: the idea that grief is an expected part of life; grief as a potential psychiatric diagnosis; death and other kinds of loss, such as the death of a loved one versus being betrayed by or broken up with by a loved one; mental health and anxiety; treatment options for mental health, including medication; empathy, love, and friendship, and how they are all essential to leading a meaningful life; different ways we experience suffering and healing. Blue Notes asks many questions about mental health and well-being, including examining the boundaries between "normal" suffering vs. mental illness. It asks if there has been a societal shift over time that has led the way for grief to become a mental illness instead of a "normal" expected outcome of life. Other questions Blue Notes examines include: How are grief, love, and empathy connected? What happens if we attempt to cure grief, and how does that affect our feelings of loss? Blue Notes will be relevant and meaningful especially to those who have lost a loved one; the grief diagnosis is very much real and being implemented all over the world. Readers who loved Agatha for its philosophy on how to lead a meaningful life will enjoy that familiar theme in Blue Notes.
