Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.

Ends in a cliffhanger
Format: Kindle
Thankfully, the next book is already available.
Roxy Collins is the queen of omegaverse slow burn. This particular series is omegaverse with wolf shifters.
Thoroughly enjoyed this book! Lots of suspense and trying to figure out what is true and what's really going on. I loved it!
Pretty spicy once the action starts. Heats are pretty much always spicy. There is a little bit of male interaction, but not full-on shmex.
Definitely recommend.
