From the Back Cover: US Secret Service Special Agent Luke Powell is lucky to be alive. Three of his fellow agents have died in unusual circumstances in the past ten weeks. Luke is devastated by the loss of his friends and colleagues, and his inability to locate the killer feels like a personal failure. He and his team are experts at shielding others, but now the protectors are in need of protection.

FBI Special Agent Faith Malone is driven to succeed and confident in her ability to solve every case she’s assigned. She’s been put in charge of the investigation into the unprecedented attacks, and with Luke’s life in danger, the stakes have never been higher. But it’s hard to know how to fight back when you don’t know who the enemy is.

Luke has teamed up with Faith before, but he’s not convinced she’s up for the job and she’s not convinced he’s telling her everything he knows. As more agents are targeted, Luke and Faith will have to learn to trust each other and work together to bring a killer to justice and prevent any more names from joining their fallen brothers and sisters on the Secret Service Wall of Honor.

My Thoughts

Lynn H. Blackburn’s new series is off to a great start with Unknown Threat! I loved the variety of law enforcement characters, from the Secret Service to the FBI. Readers of Lynn’s last series will also enjoy the cameo appearances by members of the Carrington dive team! The camaraderie of the team of Secret Service agents and the way they welcomed Faith into their group added richness to the story. I enjoyed how they worked the case together and the witty banter throughout. Some of my favorite moments were the fun interactions between Luke and Faith’s sister, Hope!

Of course, the story is also full of plenty of action! With the attacks on Secret Service agents escalating, Luke and Faith encounter danger around every corner as the perpetrator always seems to be one step ahead of them. I have to admit I was totally surprised when the attackers and their motivations were revealed; they definitely weren’t the villains I was expecting! I really enjoyed this book and will be eagerly awaiting the rest of the series.
