I got the arc of the first book in the series and was about to start it, but saw that there was also a prequel novella so I decided to give it a read. I prefer to read the prequels first, but there's a review saying it's better to read book one and then this, so we'll see how I feel when I do.
Anyway, it was cute and even shorter than I thought because it ends somewhere around 74% and the rest is the preview for The One I Left Behind. It introduces the characters we'll follow, not only in book one, but the rest of the series too.
Also, I saw someone saying how this was connected to Piper Rayne's other books, so if someone knows how I'd love to know, since this is my first time reading them.
