What she didn't expect was that this quiet, reserved knight would begin to show her a love so overwhelming she couldn't ignore it...! And so begins an unexpected journey filled with romance and adventure—between a noblewoman enlightened by her past life, and a loyal knight who can no longer hide his feelings. A romantic tale that starts with a broken engagement and turns into a runaway love story on the open road!
