Book 1 of the Chipped Trilogy:
In the year 2079, a madman has taken control of the entire world. His mission: exterminate all female life on earth. To do so, he develops a microchip that, when implanted into a woman's brain, makes her obey any order given to her by a man. If she resists, the pain caused by the chip is unthinkable. A few un-Chipped women still remain in hiding, but one must emerge and blend in with the Chippeds. But when this woman meets the resistance and learns how she can help her sex survive, she must choose between her duty to the resistance and her heart's desire for love.
