When first they meet, Neil and Zach discovered a sexual and emotional chemistry that could not be denied. Then, as mental illness consumes one, each must grow, repair himself, and work to become stronger and more independent to ultimately conquer the life-crushing consequences wrought by mental illness and emotional dependency. Chemistry is the story of attraction between lovers, the brain chemistry that determines personality and mood, the medications needed for regaining mental health, and the relationships between people who care for one another. DeSimone debut is an enthralling novel of courage, liberation, and self-realization.
