This book is sometimes listed as book five in the series and sometimes as a prequel. I would say it’s more a prequel with elements of time travel. I usually avoid time travel romances, because I don’t think I will enjoy them but this one in particular is part of a series I enjoyed so I gave it a shot. It’s probably closer to a novella than a full story, being about 150 pages. I think the length, and how quickly the story moved made it even harder for me to get into the time travel romance, or invested in either of the MCs or even the plot. It was a nice story, and most of that feeling probably came from having read the main series. I think if you were to skip this you wouldn’t miss much in the main series.
