The Darkfall Switch

After a power cut kills dozens of people in the London Underground, engineer Dan Foster uncovers a web of deception centered on a department of the US administration. The blackout may have been initiated by accident, but the trigger is part of a scheme that someone is now desperate to conceal—even if it involves murder. Foster's probes take him to the headquarters of a powerful industrial corporation in the Rocky Mountains, where he finds the plot goes deeper than he could have possibly imagined. The question is—will he be able to unveil the ugly truth before it's too late?
