The Gemini Experiment by Brian Pinkerton

The Gemini Experiment (Fiction Without Frontiers) - Brian Pinkerton

Terminally ill Tom Nolan is offered a second chance, and so much more, when he is approached by a privately funded company to become the first human to have his mind downloaded into a perfect android replica.
Sworn to secrecy, unable to even tell his family, he agrees.
But when the first test subject, a convicted felon suffering from cancer and with nothing left to lose goes rogue in Tom's replica, escaping to take his place.....and killing anyone who stands in his way.
Now a fugitive, Tom learns that there are others hunting his replica, as Russian agents race to obtain the rogue for their own purposes.......and behind it all, an even darker agenda lurks.

A breakneck science fiction thriller that hits all the marks you'd expect from across the genre, and nails every one.
Pinkerton delivers in spades, with taut writing, a compassionate protagonist, a fiendishly twisting plot, and enough dirty dealing for several novels.

Highly recommended.
