Night Shadow: A Novel (T-FLAC: Night Trilogy, Band 3)

Aside from working for T-FLAC (and having the same last name), Lexi Stone and Alex Stone are polar opposites, right down to Lexi's mere mortality and Alex's paranormal powers. And though Lexi disdains Alex's rule-breaking bravado, she can't ignore how his roguish charm makes her heart race.

But Lexi's secret desires clash head-on with her duties when suspicions arise that Alex is poised to switch sides and join forces with a European terrorist cell. Lexi is now assigned to shadow his every move, but her task becomes even tougher when Lexi and Alex suddenly find themselves partnered on an emergency mission in Russia. To stop the rise of a superhuman terrorist threat, Lexi and Alex must work as a well-oiled team, with lethal shadows looming behind them and no one to trust but each other.
