Key and Arin return in the ‘torn from the front pages’ thriller
THRESHOLD
AVAILABLE NOW
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 urgently summoned to Philadelphia. There is a threat to the Vice President of The United States. That’s all he knows. It’s what he doesn’t know that scares him:
Who made the threat? What do they have to gain? Why does someone want him involved? Is the threat real, or is someone just trying to create chaos? What the hell is he supposed to do about it?
“Fans of thrillers like the Bourne series will have a great time with Threshold.”

Suspense, Romance & Action…A Page Turner
"Great read that combines suspense , action, and some romance with great characters. A page turning story with historical and current events woven in nicely. I have read both O’Connor books and I hope there is a third!"

Thinking out of the box!
"I loved this story. It is a very well crafted tale, with historical and current events woven together. It felt so real that I was surprised that I was so emotionally invested in the characters."
"I strongly recommend this book."

Gripping, Realistic, and insightful
"I really loved the first book in the series, and eagerly anticipated Threshold being released...Threshold was a more traditional edge-of-your-seat thriller...The tension is palpable throughout the whole book, and is borderline overwhelming, but we are in the safe hands of our main characters. The balance of love, sturdy relationships, people having each others back, and optimism and determination for goodness in the face of so much turbulence is what makes this book so enjoyable. We are able to experience all this intensity, because we feel like Key, Arin, Buck, and Cat will have our backs no matter what."
