Down to Ursa: A Sci-Fi Adventure Romance by Lissa Sharpe
A sci-fi romance with high-stakes adventure, twisted biotech, outlaw space crews, and a love story written in the stars — and spliced in a lab.

Dr. Mina Smithe-Canfield’s life has taken a sharp detour. Once a rising star in mycology, she’s now a prisoner of the infamous Brethren of Blood, a nomadic crew of space raiders. Her only hope for survival? Telling a story compelling enough to convince her captors she’s too valuable to kill.

Her tale begins on the long-forgotten world known only as Earth.

Fleeing a powerful and sadistic fiancé, Mina volunteers for a high-risk scientific expedition to Earth, now an abandoned relic of humanity’s past. Her vanish into the wilderness and finally be free.

But Earth is not as abandoned as it seems.

Ursa is a man built for survival, molded by the planet, and untouched by civilization. When Mina crosses paths with this feral, magnetic stranger, their worlds collide. His curiosity could expose her, his past could doom her, and his presence threatens to unravel everything she thought she knew about humanity...and desire.

Mina must save herself, or risk everything for a man who behaves more like a wildman than a human — but who sees her more clearly than anyone ever has.


Down to Ursa is book one in the Last Man on Earth trilogy, featuring space travel, genetic engineering, high-stakes passion, and billowy nightgowns. Expect adventure, longing, and a happy-for-now ending that will leave you hungry for book two.
