I received a free copy of this book through a Goodreads giveaway! 
 4.5/5 stars 
 This book was extremely good. I haven't seen a lot of hype around its release, but it deserves some. It is so much more than what the summary makes it sound like, and it definitely surpassed my expectations! It went from lighthearted and fun moments to darker, way more sad moments with ease and kept me hooked the entire time. Kiera does a great job of telling love stories that keep the the main character central to the plot, rather than only her relationship with her love interest, and that continued through this book. Although the summary implies that this book is a romantic story, which it partially is, it is more so about Kahlen as a person and her journey as a siren, and her relationships not only with Akinli but also with the Ocean and her "sisters." I really enjoyed this book and I feel so lucky that I got to read it in advance!
