Tactical Crime Division series bundle

They handle the toughest cases in the most remote locations. They’re the Tactical Crime Division, a specialized unit of the FBI, and in these four books, the agents pull out all the stops to ensure justice!

48 Hour Lockdown by Carla Cassidy

When TCD learns of a school invasion turned lockdown, every agent is ready to engage. With children in jeopardy, the stakes couldn’t be higher. But it becomes personal for hostage negotiator agent Evan Duran when he learns Annalise Taylor is one of the captives holed up with the students in a school for the gifted. He’ll need every resource available at TCD and every ounce of his expertise to turn this disastrous situation into a rescue mission—and if he succeeds, maybe reunite with the woman he never stopped loving.

Secret Investigation by Elizabeth Heiter

When ironclad body armor inexplicably fails and soldiers perish, the Tactical Crime Division jumps into action. Agent and former ranger Davis Rogers asks to go undercover to find the traitor responsible for the death of one of his friends, and Petrov Armor CEO Leila Petrov is happy to provide access to her company…especially once she discovers she’s being framed. But will their joint efforts be enough to uncover the truth?

Midnight Abduction by Nichole Severn

When Benning Reeves’s twins are kidnapped, the frantic father knows who can help: the Tactical Crime Division and Ana Ramirez. Even though Ana once shattered Benning’s heart, the special agent is the only one he can trust. But Ana is still tormented by the unresolved case that brought them together years before—a case somehow entangled with Benning’s children. It’s up to the TCD and Ana to discover why…before it’s too late.

Secret Investigation is a HOLT Medallion finalist!

“…Secret Investigation is a fast-paced thrill ride replete with dynamic characters whose internal lives are every bit as engaging as their outer exploits. Action and attraction abound, all but ensuring that readers will lose their heads—and quite possibly their hearts—long before the last page is turned.”
– Criminal Element

“Secret Investigation might be wrapped in a small package, but it packs a big wallop with satisfyingly high stakes. Call it a post-modern, thriller take on the classic Arthur Miller play “All My Sons.” Supremely effective and wondrously realized.”
Providence Journal

“…an engaging mystery…With well-placed red herrings, Elizabeth Heiter brings this clever mystery to a shocking conclusion.”
– Book Reviews and More by Kathy

“…a riveting and realistic story.”
Military Press

“…well paced with intricate twists that kept me guessing right up until the end.”
– Avonna Loves Genres

“This fast-paced book will hook you from the first page and you won’t be able to put it down until the end.”
– Romance Librarian

“Between the title and the cover you get a good idea of what this is going to be like – a US TV cop show – think NCIS or Criminal Minds. If this story were the pilot, I’m sure the show would be commissioned.”
