Taken — Christine Pope

The choice is hers... Live life alone, or risk everything for the djinn man she loves? Jessica Monroe's time is running out.  A survivalist group is intent on eradicating Jace and all others of his kind, and it's up to her to rescue him from the stronghold of the Immune. With the survivors developing a weapon that could quite easily tip the scales in the war between human and djinn, Jessica is determined to save the man she loves -- even if means betraying what's left of humanity.
