The Space Between by Diana Gabaldon
Gabaldon is appeasing her many Outlander fans with this short novella. This is about neither Claire nor Jamie. It is, instead about Laoghaire's daughter Joan, Jaime's other step daughter and Jaime's nephew Michael and their trip to Paris.
Michael has been working for his great uncle's wine distribution company, Fraser et Cie, in Paris. Shortly after the death of his wife, he returned to Scotland for his father's death and funeral. When he returns to Paris, he is asked to escort Joan to a convent in Paris where Joan is hoping to take her orders after being a novice for at least a year.
The whispers of Joan's father Jaime, cause a case of mistaken identity and intrigue since Joan's lack of French keeps her from clarifying that he was her step-father.
This was a fun, quick read and it keeps up the anticipation of the next novel due out soon as well as the Stars series Outlander that airs in August, I believe.
