Fudge!
Format: Kindle
Titles aren’t my strong suit. Sorry not sorry.
That ending has me completely frustrated book two isn’t out yet. Just throwing that out there.
First thing first, this is a high school book where the lead is under 18. Yea yea she’s about month from being an adult, but I can’t say I would’ve even opened the file if I’d realized. It’s not a smut fest or anything, but there is sexual tension as each party figures out their emotions.
That being said, it’s a good book. There are some troubling parts, like how the supes come into their powers at 13, but most of those are dealt with in a way that makes sense. Kian is the exception. His whole arc pisses me off, especially since no one stepped in. Reflecting back on real world situations, ten or so years ago, I can see it happening, but it still makes me sick. Which, I’m sure was the whole damn point.
For the most part, Courting Darkness is a fun read. I found myself laughing along with most of the set up. By the time it started getting serious, I’d grown to like the characters enough it held an impact.
I’ll be adding book two to my list for when it comes out.

Intriguing
Format: Kindle
An intriguing story that played out slowly while introducing some unique characters. The story became quite fascinating to read as these same characters provided startling revelations to their lives. As their relationships evolve, more drama and mystery is revealed adding to my fascination. I can’t wait to read more.

Outstanding Story!!!!!!!
Format: Kindle
Oh I loved this story. Sera is such an amazing, fun character. She has so much fire inside of herself. She has humor that makes you laugh with her sassy comments. The guys are fantastic. I don’t feel as if we really have gotten to know who and what they are but they are such a mix of fae. The story is extremely well written and developed. It had me pulled in and didn’t let go. There was so much action, drama, and suspense. Then we get to the ending and goodness there is so much going on. This ending was a major cliffhanger and I absolutely can’t wait to see what happens next.

Exceptional
Format: Kindle
I think this an exciting entertaining story different from other fantasy reverse harmen story. I love the 1st book in this series and hope it continues to weave a story of friendship, love and disappointment as well as sadness. The cliffhanger was gripping and held you in suspense that waiting until the next book was released was almost too much. I’m so glad I waited to read this series until the majority of the books were released. Katie May and Quinn Arthur’s are wonderful writers and I’m looking forward to reading more from both of them.

I don’t mind a cliffhanger,
Format: Kindle
but I dropped at least one star because of the obnoxious gloating of the author after the cliffhanger.
Seriously - I don’t understand making your readers angry because you’re smug and expecting them to keep reading your books.
I was very definitely enjoying the series. Now I have a bad taste in my mouth and mixed feelings about continuing the series.
