What to read after Fallen?

Emily wakes to find that her world has plummeted into darkness -- the clouds have spilled out of the sky and taken the sun. And there is more to the mysterious fog. The mist is poison, killing everything in its path. Emily's home is no match for the caustic fog, and her family is suddenly on the run for safety. But when Emily learns that the machines built to save the world could be the cause of the accident, she turns to her father, Phil Stark, the original architect, hoping they can stop the environmental catastrophe. ~~~"Grips you from the start and doesn't let go."- Jason Gurley, Bestselling Author of Eleanor."Captivated me from the first page with its intensity... a gripping read!"- Jennifer Jaynes, USA TODAY Bestselling Author of Never Smile at Strangers."Brian Spangler has taken the terror thriller in a new and exciting direction."- Michael Bunker, Bestselling Author of Pennsylvania."Intensity from the first sentence.
