A dead man’s riddles—and secrets—thrust an FBI codebreaker into a deadly cross-country race for justice in a propulsive thriller by the Wall Street Journal bestselling author of The Cipher.

During a recent undercover sting gone bad, hit man Gustavo Toro died in the arms of FBI Special Agent Daniela “Dani” Vega. But Toro had secrets he refused to take to the grave.

In the event of his death, Toro left behind a video that promises to expose a mysterious mastermind who has been operating with impunity for decades. But there’s a catch. Dani’s team must follow Toro’s cryptic clues on a cross-country hunt for justice, and piecing together his past is more twisted than Dani could have imagined.

But as Dani and her team race to gather the evidence, it’s clear this powerful adversary will stop at nothing to keep their secrets—including eliminating those who threaten to reveal them.

Critic reviews

“Narrators Almarie Guerra and Feodor Chin find FBI agent and former military code breaker Dani Vega up to her neck in trouble as hit man Gustavo Toro dies in her arms in a botched sting operation.… Guerra portrays Dani as having a sharp mind and a hard-edged personality. Chin takes his turn, adding a sly tone and a ring of truth as the twisty plot unfolds. Bestselling author Maldonado, a former law enforcement officer, lends authenticity as she takes listeners on a cross-country chase with colorful, clever characters and a surprise at the end.”—AudioFile Magazine

“As in the previous books, Maldonado leverages her law enforcement background to lend the proceedings weight and authenticity, while flashbacks predating Toro’s death ratchet up the suspense. This series continues to impress.”—Publishers Weekly

“This riveting thriller keeps you on the edge of your seat from start to finish. Along with a solid and thrilling plot, relatable characters, and excellent world-building, the twists, surprises, action, and suspense demanded my attention.”—Mystery and Suspense Magazine

I love this series. Danielle Vega does a great job as well as her teammates. I enjoyed the fact that the “Bad guy” show a change and had a conscience towards the end. There are too many positive things for me to discuss here. I’m looking forward to the next book in the series.

When I saw Isabella Maldonaldo was releasing a new Daniella Vega book I dropped any other reading projects, borrowed a copy of the book from Kindle Unlimited that included the audiobook and settled in to go on another adventure with Dani and her FBI team.

A Killer’s Code brought several threads from the first two books in this series to satisfying conclusions and opened a few new questions that will leave me wondering if I can draw any accurate conclusions before the next book in the series shows up in my kindle.

If you enjoy police procedurals with well-developed characters who have their own human failings and issues, The Daniela Vega series is worth your time. If you’ve read the first two books in the series, what are you waiting for? Grab a copy and get some of your questions from the earlier books answered.

If you choose to listen to the audiobook version of A Killer’s Code, you are in for a treat. Narration duties are once again covered by Almarie Guerra and Feodor Chin. Both narrators are top-notch and bring Dani Vega and the other characters to life.

Dani Vega is back in an action-packed case.

I borrowed the ebook in Kindle Unlimited with the audiobook. I loved listening to the action that Dani and the FBI agents get into. I can't wait for the next book. Maybe there will be more about her family in the future, too. The narration was great, too.

Daniela Vega is fantastic
