“A powerful novel of resilience, sisterhood, and the creative strength of women.”
Raul Cuero, PhD, a distinguished international inventor scientist with more than 30 inventions, 29 patented in the United States, and author of several books on science and creativity, presents his latest literary work, Polishing Diamonds. This compelling novel explores resilience, sisterhood, and the extraordinary inherent creativity of women, while offering readers practical approaches to functional creativity, drawn directly from Dr. Cuero’s personal experiences.
At the heart of Polishing Diamonds are three orphaned sisters, each adopted into families from vastly different socioeconomic backgrounds—one wealthy and highly educated, one middle-class and educated, and one low-income with little formal education but a family of faith. Despite facing betrayal, illness, and societal obstacles, the sisters thrive through courage and ingenuity. One becomes an internationally recognized artist and fashion designer, another rises as a doctor and inventor, and the third becomes a lawyer and ultimately the president of her country. Their stories illustrate how functional creativity, determination, and courage can lead to personal and professional achievement, even in the face of adversity.
“This novel is about more than success in careers or social status,” Dr. Cuero explains. “It shows how practical, functional creativity can transform challenges into opportunities, based on methods I have personally developed and applied throughout my own life. These approaches are not abstract theories—they come from my journey of overcoming difficulties and achieving success despite humble beginnings.”
Also, with his experience as a scientific inventor, he presents in Polishing Diamonds the actions that women might take to enhance their functional creativity. This action for enhancing functional creativity in women, especially in today’s technological and AI-driven society, is also expressed in his other books on creativity, including Scientific Invention: What it Takes to Invent, set to be published this year.
Dr. Cuero’s career embodies the principles he shares in the novel. Born into modest circumstances, he became a progressive scientist, inventor, and author, recognized worldwide for his innovative work and mentoring of young people. His published books include The COVID Ghost Game (2023), Fear and Courage Today and Throughout Civilization (2023), Water and Ions as Conditions Necessary for Life (2022), How to Create: The Joy of Creativity (2015), Loneliness as a Source of Creativity (2014), and Between Triumph & Survival (2004). These works, along with Polishing Diamonds, highlight practical creativity as a tool for progress, achievement, and overcoming societal and personal barriers.
“Polishing Diamonds is a tribute to the resilience and creative capacities of women, but it is also a universal story,” Dr. Cuero adds. “It demonstrates that the same principles of functional creativity can guide anyone—men or women—to achieve their goals and align their life purpose with societal contribution. This novel reflects not a common character but a different character, shaped by unique experiences, courage, and a progressive vision.”
Written with warmth, humor, and accessible storytelling, Polishing Diamonds blends drama with inspiration. It engages readers over the age of 15, providing both a compelling narrative and actionable insights on creativity, problem-solving, and personal growth.
