These things I know.
The Vice President is coming to Philadelphia. Someone is going to try to kill her. We have four days to stop them.
Key Murphy has been summoned home to Philadelphia. There is a threat against the Vice President of the United States. That is all anyone will tell him. It is what he does not know that scares him.
Who made the threat? Why do they want him, of all people, in the room? Is the danger real, or is someone manufacturing chaos to hide something worse?
The answer is buried in a memory, deep in the neurons of Marine Captain Cat Fahey. Her ancestor faced down a similar threat in 1845 and stopped a plot to kill Frederick Douglass. Now it is Cat's turn. The plot against the Vice President is eerily like the one her ancestor foiled, and she can feel him trying to warn her across a hundred and seventy-five years. The warning has to come clear before Saturday.
The past is repeating. And the closer they get, the more they realize the threat is not what anyone thinks.
It is far worse.
"O'Connor has crafted a unique and compelling thriller that seamlessly blends history, mystery, and cutting-edge science." —Kirkus Reviews
The explosive sequel to the internationally acclaimed THE KEY TO KELLS.
WHAT READERS ARE SAYING
"So realistic I'm genuinely curious if it really happened, or almost happened."
"I thought the author would have a hard time topping the first book. Threshold is even better. Makes other thrillers pale in comparison."
"It felt so real that I was surprised how emotionally invested I was in the characters."
"Very tightly edited, not a word wasted. Highly recommend."
"Fans of thrillers like the Bourne series will have a great time with Threshold." —Readers' Favorite
Perfect for readers who love Dan Brown's The Da Vinci Code, Steve Berry's Cotton Malone series, and Diana Gabaldon's Outlander.
