Awaken me darkly

Mia Snow is part of the group of police known as AIR. they hunt aliens infiltrating their world. Her partner is injured and near death. Kyrin en Arr who is an Arcadian promises he will heal Dallas if Mia frees his sister. Mia finds out that not all aliens are bad and is drawn to Kyrin despite swearing to kill all aliens. The story was a little formulaic but I still really enjoyed it.
