Frequency is a very unique story about Myssa discovering who and what she really is after suffering the unimaginable death of her sister. This is unlike anything I have read, and I really enjoyed it. It is an EXTREMELY slow burn, just waiting and waiting and WAITING for these characters to finally accept their feelings and join together. It is worth it when they finally do though. Myssa and her best friend, Vix, are so fun together and I love their friendship, bond, and loyalty to each other. Same goes for Knox and Zayne. I am invested in these characters and I cannot wait to read Fractured, since Frequency left me on a bit of a cliffhanger. I've gotta see what happens next. I only gave it four stars instead of five because I felt parts of the story were repetitive, and drug on a little too long, and my kindle version had multiple typos/grammatical errors (I'm just going to blame that on the kindle version though, I have had that happen before and the physical book be completely fine!) but I enjoyed it over all. Moving on to Fractured, can't wait to see what happens next!

Fractured completely stole my heart. While I enjoyed Frequency, this book took the story to another level. Getting the backstory added so much depth to his character, and seeing the events that shaped him made me understand and empathize with him in a way I never expected.

The first half focuses heavily on character development, but it pays off beautifully. Their relationship was both heartwarming and heartbreaking, and I felt every moment of their journey.

Shan Lynn's writing made Aetheriem come alive, and I loved learning more about this world and its characters. The ending left me desperate for the next book, and I honestly can't wait to see where the story goes from here.

A beautiful mix of fantasy, romance, and heartbreak. This series just keeps getting better. ❤️✨📚

I loved the vibes of this book. It reminded me of the 2000's/10's urban fantasy that used to have me in a chokehold.  The MCs and their sidekicks are all a lot of fun. If you love a man who years, this book has you covered. The mystery/plot is quite unique and I'm looking forward to finding more out in book two. This does end on a cliffhanger and it seems like you'll have to read the whole trilogy for the whole story. I'm jumping into book 2 right away, and hopefully the third book comes out soon.

This was a good story that was a VERY VERY slow burn. While it was a quick read, the burn was a little too slow for my liking. I enjoyed learning a bit about the characters who were all likable and Aetheriem but I wish there was a bit more. That said, I did not waste time jumping into book 2, “Fractured” as I was wanting to know more and find out what happens next!

Umm, holy crap. That was intense! I couldn’t put this down. The story sucks you in and doesn’t let go. This was such a unique and intriguing concept! I extremely enjoyed it. You could feel the sexual tension and slow burn radiating off the page. And that cliffhanger!!! I’m in agony now. Just brutal. You must read this book. ASAP. I received an advance readers copy of this book and I'm leaving this review voluntarily.

Myssa's story had me completely captivated from the very first page. Her emotions are so vividly written that you feel every heartbreak, triumph, and struggle right alongside her. This is one of those books that's impossible to put down once you start. The characters and story pull you in and refuse to let go. I flew through it and immediately wanted more. I can't wait to pick up the next book in the series!
