Retribution. Also known as "payback" or a more dated word: "vengeance." Arnaldo Soto has taken Emilio and intends to use him as bait to trap Gemma. It's an effective strategy, because Gemma will do anything—anything—to save the young boy.

The woman known as Gemma Keyes is gone, her molecular structure destroyed and reassembled as . . . something else. In Gemma's stead emerges a fierce weapon: part woman, part nanotechnology, her cellular composition conjoined with the nanocloud, indissoluble and formidable. She and the nanomites are now more than a match for her enemies—but Gemma has promised God that she will not strive to visit retribution on Arnaldo Soto for taking Emilio.

The nanomites have made no such promise.

The third installment in the Nanostealth series will blow your mind.
