Rookie Instincts by Carol Ericson

New TCD team member Aria Calletti is determined to find out why women are turning up dead—especially since an infant was left at the most recent crime scene. Fortunately for the TCD's newest operative, the baby's uncle, Grayson Rhodes, has sacrificed everything to discover the truth following the disappearance of his half sister. But can a civilian-turned-undercover-dockworker and a brand-new agent take down a formidable drug kingpin?

Toxin Alert by Tyler Anne Snell

Following a deadly anthrax attack, TCD's biological weapons expert Carly Welsh springs into action. Problem is, the Amish trust no one—especially not an FBI special agent. That's where Noah Miller comes in. Even though the rancher left the fold decades ago, the community trusts him...and so does Dr. Welsh. But even their combined courage and smarts might not be enough against sinister forces that want them both to perish.

Impact Zone by Julie Anne Lindsey

Veteran TCD special agent Max McRay is the definition of unflappable. But when a serial bomber wreaks havoc in the town where his ex-wife, Allie, and infant son live, suddenly a high-profile case becomes personal. The bomber is ruthless...and now Max's family is in his sights. Can the TCD stop this killer's deadly rampage before Max and Allie pay with their lives?

Hunting a Killer by Nicole Helm

When K-9 handler Serena Lopez discovers her half brother's a fugitive from justice, she must find him—and his dangerous crew. It's a good thing that her partner is infuriatingly efficient and handsome lead agent Axel Morrow. But as smart and cunning as the duo may be, it's a race against time to catch the armed and dangerous criminals before they kill again.
