CODE BLACK.
The White House has been breached.
Assume the worst.

The President has left for a secret bunker with his most trusted agents and officials, dedicated to keeping the US government intact at all costs.

But what if the danger was there with the President the whole time?

Erik Hill has given his life to the Secret Service, but years of dealing with Washington sleaze have left him burned out and ready to quit. Yet with no one better equipped to take on the threat to his government and his country, Erik can't ignore his calling.

But Erik has never faced a threat like this. With traitors in the midst of government, and killers ready to strike inside the presidential bunker, it will take everything Erik has to save his leader, his country - and himself.
