The next novel within an alternate history series where Teddy Roosevelt is president once again before WWI breaks out, and on his side is the Dark Chamber, a secret spy network watching America’s back. After foiling a German story to devastate America’s coastal metropolitan areas from Boston to Galveston, crack Dark Chamber agent Luz O’Malley and budding technical genius Ciara Whelan head to California to recuperate. But their well-deserved relax is cut brief from the discovery of the diabolical new tool about Theatre of Spies that could give the German Imperial Navy order from the North Sea. Luz and Ciara must go deep undercover and travel across a global at battle, and live under false identities in Berlin itself to ferret out the project’s secrets. Close on their trail may be the harmful German agent codenamed Imperial Sword, who is determined to obtain his revenge, and a band of assault-rifle equipped stormtroopers, led by the murderously efficient killer Ernst Rohm. From knife-and-pistol duels on airships to the horrors of the poison-gas factories to harrowing sea fights in the North Sea, the combat continues–with a world as the prize.
