I received The Edge of the Abyss by Emily Skrutskie through NetGalley in exchange for an honest review, and I give it 4/5 stars.
It took me a long time to get through this book, not because I wasn't into it, but because I breezed through the first book and then fell into a weird book lull. Overall, though, this was a great read.
The best thing about this duology is that each chapter has a purpose and some sort of tension that drives the story forward. The pacing is phenomenal and the characters are likable, real, and morally-complex. The world could benefit from being fleshed out a bit more, but I enjoyed it and found it interesting.
The main thing I wasn't sold on was the Cas/Swift relationship. It just felt problematic to me since Cas was essentially a prisoner, even in the second book. In addition to being "eh" about that, the twists in the story were a bit predictable, but still managed to elicit a silent cheer/fist pump when they happened.
Ultimately, I liked how the story was concluded and I recommend this.
