The story of Ryder, Greyson's best friend, and Sadie, Juno's sister and Greyson's sister-in-law, continues a few months after the conclusion of the first book in the series. Ryder and Sadie's story definitely moved faster than Greyson and Juno's mainly because we already had the backstory of the Silver Moon Pack and Juno's unique gift as a laighir. In this book, Sadie comes to learn about shifters, what her gift of being a laighir means, that her sister has become a shifter, and she's the fated mate of Ryder, though she's still attracted to Thayer, a shifter from another pack. This is a lot of unusual information that Sadie learns from Ryder and Thayer and has to digest quickly because she's in danger. Although her sister, Juno, is pregnant, I did not get the impression that her pregnancy was delicate or stressful, so I'm not sure why Sadie didn't call her sister just to confirm the unusual circumstances? Additionally, when Ryder, Sadie and Thayer realized she was in danger, they still kept Greyson and Juno in the dark. These are the two main reasons I rated this story as 4 stars instead of 5 because I did enjoy the sexual tension and the constant suspense and adventure these three faced.
