NIKI UNDERCOVER (A Niki Undercover Thriller #1)

PUBLICATION DATE September 16, 2025

Two years undercover. One phone call. Zero margin for error.

Posing as Niki Foster, FBI Agent Ashley Prescott earned the trust of Patriots for Freedom, an extremist militia planning to tear America apart. She's their Chinese linguist, arms dealer contact, and the Bureau's only window into a far-reaching conspiracy.

Then her estranged billionaire father destroys everything with a phone call—using classified intel that could only have come from inside the FBI.

Cover blown. The Bureau wants to pin the leak on her and shut down the mission. But Ashley knows the real threat: the militia leaders will disappear, the arms shipment remains a threat, and the traitor will ruin other lives.

Racing between Minnesota to hunt down her father and D.C. to maintain her deadly undercover masquerade, she has ten days to expose the mole and stop the conspiracy. With ex-SEALs closing in and her own agency against her, going rogue is her only shot at getting justice—and surviving.

When the system turns against you, justice becomes a one-woman war.

NIKI UNDERCOVER launches an explosive new thriller series for fans of Isabella Maldonado and Karin Slaughter.

What Readers Are Saying

This is a fantastic and amazing read!! I absolutely love it. the complexity of the characters and the story had me hooked from the start and I found myself unable to put it down. Edge of your seat and addictive, can't wait to see what could possibly happen next kind of read. If you haven't read it yet then you definitely need to. one of my many handful of new favorite reads of the year hands down.

~ Sherlene, Goodreads Review
I loved this book. Niki Undercover is a thrilling who dun-it. It had me guessing to the end. The manin character is brilliant and resourceful. I really enjoyed the secondary character - Seamus McCree. This book has a great plot and the ending is very satisfactory.

~ Mark, Bookbub Review
Rapid action from very beginning. Characters have depth and even a sense of humor. The plot is intense and moves rapidly with military precision. You will more than get your moneys with this novel.

~ Lori, Goodreads Review
I really enjoyed this story and look forward to the others in this series. I liked that Seamus appears in the book, too, although you don’t have to read the Seamus McCree series to enjoy this one. Between Niki’s FBI assignment and the issues at her father’s business, it’s non-stop action.

You won’t be disappointed.

A Note from Jim about the Seamus McCree series

I’m often asked by people unfamiliar with Seamus McCree and his friends and family which book they should read first. Before I answer, I ask a question of my own: “Do you prefer to read series in order?” If so, start with Ant Farm. (The books are in alphabetical order to make them easy to sort.) In Ant Farm, Seamus accepts his first field assignment, and readers meet his son, Paddy, and his arch-nemesis, the Happy Reaper.

Some people don’t care a whit for chronological order and press on, asking something like, “Which is the best?” or “Which is your favorite?” My favorite story is the one I’m currently writing. When I complete that one, my favorite changes to the next story. As for which is the “best,” opinions vary. You’ll have to read them all and decide for yourself (and drop me a note and let me know your favorite).

Some folks are drawn to a particular cover (check them out below) and choose to enter the series midstream. Others read the blurbs and choose based on the hook that grabs them. Others want to read a book set in Michigan's Upper Peninsula, and I'll suggest Cabin Fever. However you choose, I hope you’ll enjoy the story.
