Check out at the library, the first book from the series Stone Braide Chronicles.
“In post-apocalyptic America, Selah Chavez is crouched in long grass on a shore littered with the rusted metal remnants of a once-great city. It is the day before her eighteenth Born Remembrance, and she is hunting, though many people refuse to eat animal flesh, tainted by radiation during the Time of Sorrows. What Selah’s really after are Landers, mysterious people from a land across the big water who survive the delirium-inducing passage in small boats that occasionally crash against the shoreline. She knows she should leave the capture to the men, but Landers bring a good price from the Company and are especially prized if they keep the markings they arrive with.”
