So first of all, it's hard to give this book the review it deserves since it's the fifth and final one in the series and doing so would give all kinds of spoiler away. That being said, I looked back at all my ratings and each book has garnered at least 4/5 stars with the last two capturing a complete 5/5 from me. I think that shows what a strong series this has been for me and how much I have loved it. And while I am sad to see it over, man, what a ride.
I'm not going to mention the plot, but will go as far as saying that this installment introduces us to some pretty awful characters (some we thought were dead) some terribly horrible supernatural creatures (the sluagh) and tow Dryads who add comic relief in a book where you wouldn't expect it. In fact, Helia and Alexios are such a great addition to this tale and I truly enjoyed every scene they were in. Finally, I have to address the love triangle. There is a strong one in this book but because it has been woven so delicately into the Fae folklore and prophecy, it was not annoying or overwhelming. In fact, it is very well developed and there is absolutely no insta-love. And I waited 5 long books to find out how this element played out and can I say I'm thrilled with the conclusion. In fact, I'm so happy with Liv's decision, I may have jumped up and down. Also, I love that fact that Armstrong doesn't wait until the very end to disclose this wrap-up and that once its is disclosed, it continues to be worked into the plot.
So if you can't tell, I would highly recommend the Cainsville series. I've read the entire Women of the Underworld series (minus a few short story/novella collections) and while I loved it as well, Cainsville clearly outdid it. Plus, there's an adorable Fae Hound in this book who I dearly love.
