Shades

Maria is an outlaw. She lives life as it comes at her, so when she meets someone she doesn't know what to do with, her life is thrown completely off-kilter.

Shadow is an plain-clothes recovery agent for a top secret government facility based in Nottingham, England. When he is doing some work in Arizona, he comes across a specific target that is said to be a High Security Risk for the entire world.
Personally he doesn't see it like that at all. Only the possibility that he is in immediate danger from her, and certainly NOT because of what the facility told him.
