excellent

Literally couldn’t put this one down. I’ve loved this series from the first Rivers Edge series to now.

I’m so glad there’s a HEA for all the shifters and people who were at the mercy of The Lab.

Highly recommended series.

Wonderful read

Loved meeting Riggs and his mate Niles. Their love was like the others in this series. Unexpected and unique to the characters. Loved seeing old friends from the previous books. Honestly if you like shifters and romance give this whole series a try.

I enjoyed the River's Edge series and this wasn't bad either. I just expected the ending to have .ore details. How Rigg was able to get insider information was great but the execution of the takedown needed more details.

3.7 the book was good but I didn’t enjoy it as much as the first too again it’s just really short and not enough descriptions. But the couple and family was very cute

I enjoyed this book. I thought it was a good addition to the Beyond River’s Edge Series, set in the same universe of the River’s Edge Series. I think that this is the last of this series but I’m hoping it’s not the last we’ve seen from this universe. I thought Rigg and Niles were cute together. This book is exactly the insta-love, low angst story that I expect from this universe. Rigg, just like Willy and Daxton (Book 1 & 2) is very unique, he was not only created in The Lab but he doesn’t have any beast, since he’s not a animal shifter but a human one and can shift into any human. Rigg found two very young shifters, Lily and Connor who were from a lab and saved them. He’s been working alone to try and take down the lab, so he and the kids can finally be safe.

While he’s planning to meet someone who’s possibly similar to him in a bar the last thing he expects is to meet his mate, a wolf shifter named Niles but fate sure knew what they were doing bringing them together now. Niles completes their family perfectly and he takes the news of Rigg’s being different, as well as becoming an insta-dad to two special toddlers extremely well. I enjoyed getting snippets of some of the characters from the River’s Edge pack. I’m looking forward to reading more books from both authors in the future. I’d definitely recommend this book, series, universe and author to everyone.
