Fallen

When a group of rogue djinn attack the sanctuary of Taos, New Mexico, Jessica Monroe has no choice but to activate the device that was designed to destroy the elementals’ supernatural powers. With her lover Jace and the other friendly djinn in Taos doomed to a weakened half-life as long as the machine is active, Jessica and the other members of the community launch a desperate mission to retrieve the one man who might be able to help them — Miles Odekirk, the scientist in Los Alamos who invented the device in the first place.
The threat of retaliation by the Los Alamos survivors is only one of the perils facing Jessica, however. For Jace has his own enemies, and when an ancient rival returns to seek his own revenge, Jessica may have to make the ultimate sacrifice to save not only the man she loves, but everyone in the Taos community, human and djinn alike.
