Carrier by Anne Tibbets

Twenty-two -year-old Naya has spent nearly half her life as a sex slave in a government institution called The Line. When she’s kicked out after getting pregnant with twins, she’s got no way to earn a living and a horrifying choice to make: find someone to replace her, or have her babies taken in her stead.

A doctor with a history of aiding ex-Line girls, Ric Bennett, wants to help. He runs a team of rebels that can delete Naya’s records and free her forever. But when The Line sniffs out his plan, things get bloody, fast. Naya means more to them than just a chance at fresh faces—her twins are part of the government’s larger plan.

As they hide from government search parties, Ric comes to admire Naya’s quiet strength. And Naya realizes Ric might be a man she can trust. If they make it off the grid, they could build a new life. But first they’ll have to survive the long, vicious reach of The Line.
