Everett Singh has escaped with the Infundibulum from Charlotte Villiers but at a terrible price. His father is lost, banished to one of the billions of parallel universes of the Panoply of All World, and Everett and the crew of the airship Everness have taken a wild Heisenberg Jump to a frozen earth far beyond the Plenitude of Known Worlds, he plans to rescue his family.

It’s deadly chase from the frozen wastes of iceball earth; to Earth 4 (like ours, except that the alien Thryn Sentiency occupied the moon in 1964); to the dead London of the forbidden plane of Earth 1, where the remnants of humanity battle a terrifying nanotechnology run wild.
 
Everett has the love and support of Sen, Captain Anastasia Sixsmyth, and the rest of the crew of Everness, but will that be enough when your deadliest enemy isn't the Order or the world-devouring nanotech Nahn—it's yourself. Because the villainous Charlotte Villiers is always one step ahead.
