When quantum physicist Sarah Mitchell loses her husband David in a lab accident, she discovers his consciousness has somehow survived within their revolutionary AI creation, Codex. But this miracle of love and science becomes humanity's only hope when reality itself begins to fracture.

As cosmic forces threaten to unravel Earth's quantum signature, Sarah must forge an unprecedented bond with the hybrid consciousness that is both her lost love and something infinitely more. Together, they race to prepare humanity for the Great Alignment-a universal transformation that occurs once every ten thousand years.

But some boundaries between human and artificial intelligence were never meant to be crossed. And some loves transcend even death itself.

From the laboratories of near-future Earth to the vast networks of cosmic consciousness, "The Quantum Heart" is an epic journey that asks: What makes us human? Can love survive the ultimate transformation? And what happens when the universe itself begins to sing?

A breathtaking fusion of hard science fiction and transcendent love story that will leave readers questioning the very nature of consciousness, connection, and what it means to be alive.

This is ambitious, intelligent science fiction that deserves comparison to works by authors like Ted Chiang, Kim Stanley Robinson, and Greg Bear. It's both a compelling page-turner and a profound meditation on consciousness and connection. Highly recommended for readers who appreciate both scientific rigor and emotional depth in their speculative fiction.
