Hunted — Rachael MacKay

The year is 2201, but utopia is distant memory. Earth's population is a fraction of what it was, following a long war with an alien race, who left as unexpectedly as they arrived. War veteran Alexandra Beckett makes a living putting her knife skills to use as a tracker, a hunter for hire in a dangerous new world of large mutated beasts. Beautiful, fierce and deadly, she unwittingly attracts the attention of secret cabal of powerful people who mean to use her gifts for their own ends. The hunter is now the hunted.
