Rosslyn Station: A Detective Kiki Diaz Thriller

Rate this book
After a successful undercover operation ensnared an MS-13 gang leader in a high-profile human trafficking investigation, the case is picked up by the feds, and Fairfax County Police Detective Sergeant Kiki Diaz prepares for a complex federal trial in Washington, D.C. The ordinary way to get from her townhouse in Fairfax to the courthouse downtown is via the Washington D.C. Metro, but this journey turns out to be anything but ordinary.

By the third stop on the Metro's Orange Line, Diaz notices passengers filling up her train that don't exactly fit the profile of Washington's typical government commuters. These gangbangers are up early - and up to no good when all hell breaks loose at Rosslyn Station, last stop in the Commonwealth of Virginia.

This fast-paced thriller alternates between Kiki Diaz's first ten years with the police department and her harrowing experience - initially just to survive long enough to get downtown, but to thwart what appears to be a coordinated attack on her, the Metro system, or even the White House itself.

Growing up in Fairfax County made this story hit close to home. The dual timelines—past and present—intertwine seamlessly, building tension and momentum with each chapter. The protagonist is both relatable and easy to root for, making this a fast, compelling read that kept me flipping pages.

First time reading this author

I didn't know what to expect when I started reading this book. I haven't read many law enforcement books in the past, but I rather enjoyed this one. And I look forward to reading others in this series.
