FBI Joint Task Force Books in Order

FBI Joint Task Force is the part of Fiona Quinn's Iniquus world that leans into modern espionage, the way influence, technology, and narrative can be weaponized. These are romantic suspense novels, but the core tension is often about information, who controls it, who believes it, and what happens when it spreads.

In this series, a post can be a weapon.

Open Secret introduces the tone with an operation tied to psychological warfare, where social media and video games become tools for recruitment and destabilization. The romance runs alongside the case, but it never feels detached from the danger because the heroine is pulled into the mission as an asset, and then becomes a target.

Cold Red shifts into survival suspense. An undercover operative and an injured FBI agent are forced together after a crash, with terrorists closing in and a winter storm making every decision worse. The relationship builds in the space between distrust and necessity.

Even Odds brings the task force back into undercover work, using a fake relationship to get close enough to stop a larger threat. The tension is personal as well as operational, and the book leans into the idea that the most dangerous lies are the ones that start to feel real.

These books connect to the wider Iniquus world through shared organizations and recurring names, but you can follow the series without reading anything else. The cases are designed to resolve, even when the larger universe keeps moving.

If you like romantic suspense that feels timely, full of conspiracies, high-level stakes, and characters trying to outthink the next move, FBI Joint Task Force is a strong fit. Read in order for the cleanest arc, but expect each book to deliver its own complete mission.
