FINAL INVENTION

"My final invention isn't finished."

For decades, historians assumed the phrase referred to unfinished personal projects.

They were wrong.

Young historian Sarah Collins discovers that each scientist left behind a fragment of a much larger design. None of them possessed the complete blueprint. Each had been working on a different component without knowing the identities of the others.

When Sarah connects the fragments, she discovers the existence of Final Invention—a machine designed to manipulate fundamental physical forces.

It could transform energy, matter, transportation, medicine, and communication.

But it could also destabilize the physical environment itself.

Someone has already begun assembling it.

Sarah races across America following clues left inside laboratories, patents, journals, and private collections. With powerful organizations closing in, she must discover why the original scientists deliberately divided the invention among themselves.

The answer may be hidden in the final component.

And the final component may already be inside Sarah's possession.
