The Eden Trilogy

 Cities have become the most dangerous places on Earth, infested with thousands of Bane, and people must now survive in the mountains and wilderness. But ammunition and medicine are essential to survival and they don’t grow on trees. Eve, as an elite defender of Eden, must go on a raid with a small team into the city for supplies that will keep their people alive. But this dangerous world is evolving and the rules that once kept them safe are changing.
