During their time traveling, they met a stranger who changed the course of their mission permanently. The author of this book Jodi Taylor has written many detailed books in the past such as Christmas Present and About Time.
This one is a short story which we usually don’t see in the author’s creation thus it was a new experiment by her. Zara Ramm is the official narrator of the series and she too had to bring some changes in order to narrate this short story. Though it is a short story it has not disturbed the spice of the series.
