Silicon Heartbeats is out now — available in paperback and eBook.
After witnessing a devastating medical error and watching his grandmother narrowly survive a misdiagnosis, Stanford PhD student Alex becomes determined to solve one of healthcare's deadliest problems.
What begins in a small, leaking office south of San Francisco grows into Vitanova, an AI-powered medical startup poised to transform diagnostic medicine. As the company rises to prominence, Alex finds himself caught between ambition and loyalty, innovation and ethics, success and the relationships that once defined him.
As the stakes rise, Alex is forced to confront a question that no technology can answer: What is the true cost of changing the world?
“It may be that when we no longer know what to do we have come to our real work, and that when we no longer know which way to go we have come to our real journey.”
— Wendell Berry — epigraph of Silicon Heartbeats

For readers
Who will love this book?
Silicon Heartbeats is a debut literary novel for readers who want more than a startup story — a book about people, choices, and what success is allowed to cost.
If you follow Silicon Valley for the drama as much as the disruption — the late nights, the pitch decks, the friendships strained by scale — this novel was written for you. It is set in the world of medical technology and artificial intelligence, but the engine of the story is human.
Readers of contemporary literary fiction, book-club fiction, and thoughtful tech narratives will find familiar ground: ambition, love, loyalty, and the slow reckoning that arrives when a company grows faster than the life around it.
You do not need a background in medicine or machine learning. The book is written for anyone drawn to stories about founders, families, and the moral weather of building something that matters.
Expect a reflective, character-driven pace rather than a thriller. The tone is intimate and cinematic — Silicon Valley urgency giving way to quieter questions of meaning, place, and what remains when the metrics finally stop moving.
A change of light
Between the rush of Silicon Valley and the slow gold of the Mediterranean lies a question worth a whole life to answer.
Where the story is headed is something only the last page will tell.
The Author
Alessandro Sappia
Alessandro Sappia is a writer drawn to the human stories behind technology — the ambition, the sacrifice, and the search for meaning that no algorithm can optimize.
Silicon Heartbeats is his debut novel: the story of a med-tech founder who sets out to change medicine, and the human questions that ambition leaves unanswered.
He writes at the intersection of innovation and intimacy — where breakthroughs in AI and healthcare meet the older problems of trust, love, and what we owe the people closest to us. The novel grew from a simple conviction: the most important systems we build are still measured in human lives.
“I wanted to write about technology not as an abstract force, but as something built by people under pressure. Silicon Heartbeats is about AI and medicine, but at its core it is about ambition, love, loss, and the difficult question of what kind of life is worth building.”
