Cold Truth by Toni Anderson

Librarian and amateur sleuth Rowena Smith never expected her search for her biological father to end in murder. But when her research leads her to a bloody crime scene and the card of FBI Supervisory Special Agent Kurt Montana, she makes a desperate call for help.
Kurt, a hardened FBI Hostage Rescue Team leader, is ready to head home after a failed undercover op—until Rowena’s voice stops him cold. Minutes later, the flight he should have been on crashes, killing everyone onboard. Kurt knows one thing: Rowena just saved his life.
Now they’re on the run through southern Africa, hunted by powerful, unknown enemies who will stop at nothing to keep the truth buried. Forced into hiding, they fake a relationship to stay one step ahead—but their chemistry is all too real.

As danger mounts and secrets unravel, their fake romance turns into something raw, intense, and deeply personal.
