Tasked with neutralizing a lethal bioweapon, she turns to the one person capable of helping her stop the threat of pandemic in time: the love of her life, back from the dead and mad as hell at her supposed betrayal. Recruiting Cole to save millions of lives may be harder than resisting the attraction still burning between them, but Maddox will do whatever it takes... even if it destroys her. When Maddox crashes back into Cole Matthews' life, he wants to fight back. He wants to hate her. But the crisis is too strong to ignore, and soon the two former lovers find themselves working side-by-side in a breakneck race to stop a world-class killer with a secret that could end everything. The clock is ticking.
