Their Last Hope - Sarah Ettritch

AI specialist Liz Price is determined to see sentient androids in her lifetime, but then she’s diagnosed with terminal cancer. Hoping that her dream will be realized in the future, she arranges to be cryogenically frozen upon her death.

When Liz is revived years later, she expects to be cured. But sentient androids are taking humans and killing them for some unknown reason. They control the medical system, and they don’t treat serious illnesses.

A resistance group wants Liz to turn the androids back into mindless machines. They tell her that’s the only way to stop the androids, and the only way she’ll be cured.

Liz wants to live, so she agrees to work with the resistance. She secretly hopes she can reason with the androids, but then she finds out why they’re taking humans.
