Rome's Revolution is a three-part interstellar adventure featuring a man from the 21st century and a woman from the 35th century who band together to fight forces dedicated to the extinction of mankind. Cinematic in scope, Rome's Revolution offers romance, comedy, heart-pounding thrills, suspense, "legal" time travel, and meticulously researched hard science. It is a love story and a culture clash. The entire Rome's Revolution Saga has everything you love about hard science fiction: robots, aliens, computers, genetic manipulation, spaceships that travel faster than light and some that travel a lot slower.
Rebirth (Book 1 of The Rome's Revolution Saga) chronicles the adventures of Rei Bierak, a young man from the 21st century who wakes up 14 centuries from now, only to discover that everything he knows about the universe is wrong and he is nothing but a despised relic from the long-dead past. Rei, along with 542 other humans, was frozen and launched in the Ark II toward the stars with the hope of establishing a colony on a habitable world in the Tau Ceti system. During Rei's long trip, modern civilization has collapsed, and society has reformed into a decidedly different model. The 24-chromosome mind-connected humans of the future called the Vuduri are efficient, indifferent, and emotionally deficient. Devoid of nearly all the traits that make us human: art, music, even speaking, the Vuduri have conquered faster-than-light travel and have established an outpost in the Pi3 Orionis system (aka Tabit) to study why certain stars are disappearing. Awakening 1388 years in the future, Rei meets Rome, a beautiful half-breed Vuduri woman, who is eventually ostracized for consorting with him. Rei and Rome are joined by OMCOM, a super-computer with delusions of omnipotence. Together, they fend off a hostile society, saboteurs, and technology indistinguishable from magic. The fate of humanity, perhaps even life itself, hangs in the balance.
If you are looking for some science in your science fiction, this book is for you.
