Since losing her great love to the Queen of the Sainted Isles, Arden must fulfil an impossible promise before she can return home – she must complete the dangerous Rite that will return Jonah’s spirit to the abyssal Court of the Deepwater King.

This sets her off on a journey far out at sea to find believers of the old religion on the oil-slick and mysterious islands beyond the horizon. But such a responsibility will not come without sacrifice, for the Deepwater folk who worship the King require the most desperate payments the soul, and with one man Arden may have to pay the greatest price of all…

Astonishingly original, with world-building to rival the depths of the ocean, McKenna has drawn a rich tale of longing and courage – penning the perfect oceanic steampunk fantasy.


Deepwater King is the second instalment in the beautiful Monstrous Heart trilogy by Claire McKenna. Monstrous Heart is a book that’s been on my radar for quite a while and I ended up reading both books back to back. Deepwater King picks up immediately after the events of Monstrous Heart and I found it so easy to get sucked back into the story. We are once again following Arden as she heads out on her journey to complete the rite and return Jonah’s spirit to the court of the deepwater king.

While I really enjoyed Monstrous Heart I enjoyed Deepwater King even more. The world is so unique and – it’s a Victorian-style world full of mysterious sea creatures and fascinating abilities. The blood magic was something that I was particularly intrigued by and the way McKenna incorporated that into the world. I liked that we got the opportunity to learn more about it as the series progressed. It took me a little while to get to grips with the world in book one so I found it much easier to understand what was going on in book two. McKenna has an absolutely beautiful writing style and the vivid writing really made the story come alive.

Arden is an interesting protagonist – she’s the light mistress and in this second instalment there is danger wherever she turns. She’s quite a strong-willed main character and she will do whatever she can to fulfil her promise. She has been on such a journey since the first book and I really enjoyed seeing the character development. I also liked Jonah who is much more than we first suspect in Monstrous Heart. Deepwater King is definitely a book I found myself thinking about when I wasn’t reading it and I was always desperate to get back to the story. I ended up reading the last hundred pages of the book in one sitting, and I am desperate to see how it all ends in the final instalment. If you’re looking for a captivating fantasy story with plenty of twists and turns, this is definitely one to check out.
