Passion's Timeless Hour — Vivian Knight-Jenkins

HEALING ANGEL
A gifted and dedicated army nurse, Rebecca Ann Warren had committed herself to saving soldiers wounded on the killing fields of Vietnam. But when a freak accident propelled her back to a Civil War battlefield, and into the arms of a dashing Southern officer, she discovered long-buried desires that she could no longer deny.

REBEL LOVER
Sworn to defend the Confederacy, Alexander Ransom would let nothing stop him from completing a secret mission he had undertaken --- until Rebecca stole his heart. But his growing love cooled when he began to suspect that the spirited young woman might be a Yankee spy. And soon Rebecca realized that the only way she could prove her innocence was to convince Alex of the impossible . . . that she was really from another time, another place.
