A new take 🤔
Format: Kindle
I’m not going to go into what this book is about — by now you e already read the synopsis and have an idea — but I will give a couple of insights.
Definitely a different take on angels and their fall; I like it. This is an interesting start to a new series - YES, this does end on a cliffhanger so be prepared for that. I’m eager for the next book (and hopefully the last in this series — sometimes the author(s) will switch it up depending on how the story flows for them) in this series.
I’m hoping that a certain male character redeems himself because he’s a dick that will make the meaning of mixed signals jealous lol.
You ever watch that old movie — I think it’s call Mommy Dearest? — yea, let’s switch that up to daddy. That man would make a perfect husband to mommy dearest.
I recommend this book because while these authors are well known for their cliffhangers, they are also well known for putting out good stories.

Liked it
Format: Kindle
I liked the worlds and the characters. The prophesy is confusing in that I would think, since all worlds ore on a path to destruction, the angels would want their world to be saved. I am sure there is more evil that will be revealed as the series proceeds. I dislike a prolonged “poor little me” trope and the main character has moved past that, thankfully, and began to show a fierce attitude as the novel progressed. The last portion of the novel had some great action. It’s worth reading, just be patient with a slow start.

Great start
Format: Kindle
I loved this book! It's funny but still deals with tough themes, like chronic illness, a serial killer on the loose, and a dash of self-harm. The guys are interesting and distinct, we don't know too much about them yet. It does end on a really terrible cliffhanger but on the bright side the next book is out and I believe the series is complete. I have enjoyed both of these authors separately and this is a great team up!

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.
