Counterpart — Hayley Stone

The high-intensity sci-fi thriller series that began with Machinations continues as reincarnated insurgent Rhona Long faces off against the one enemy she can't outwit: her own clone.
 
The machines believed their extermination of the human race would be over as quickly as it began. They were wrong. As the war against extinction intensifies, people are beginning to gain the upper hand.
 
Commander Rhona Long understands survival better than most. Killed in combat, she was brought back to life using her DNA, and she's forged a new, even more powerful identity. Now the leader of the resistance, she's determined to ensure the machines are shut down for good.
 
But victory is elusive. The machines have a new technology designed to overcome humanity's most advanced weaponry. Despite Rhona's peacekeeping efforts, former nations are feuding over resources as old power struggles resurface. Worse, someone inside the resistance is sabotaging the human cause -- someone who, from all appearances, seems to be Rhona . . . or her exact replica.
