Book Description: A beautiful discovery outside the window of her underwater home prompts the reclusive E. to begin a correspondence with renowned scholar Henerey Clel. The letters they share are filled with passion, at first for their mutual interests, and then, inevitably, for each other.

Together, they uncover a mystery from the unknown depths, destined to transform the underwater world they both equally fear and love. But by no mere coincidence, a seaquake destroys E.’s home, and she and Henerey vanish.

A year later, E.’s sister Sophy, and Henerey’s brother Vyerin, are left to solve the mystery of their siblings’ disappearances with the letters, sketches and field notes left behind. As they uncover the wondrous love their siblings shared, Sophy and Vyerin learn the key to their disappearance – and what it could mean for life as they know it.

Review: While I used to think I didn’t enjoy epistolary-style stories, I’ve read a number of really great ones over the last few years to the point where I’m now wondering if I had originally just read a few not so great ones and judged the entire format just on that. As it stands, the “Emily Wilde” series has done a lot to reform my opinion, and this one sounded very similar, not only using a similar format but also leaning heavily into the academia side of fantasy and science fiction. Let’s dive in (heh, how clever)!

I think this will be one of those books that might be a struggle for the average fantasy reader, but will also garner devoted fans who also adore it! This largely comes down to the overall style and tone of the writing. Like I said, “Emily Wilde” is definitely a comparable title, but in comparison to this one, that is “epistolary academia fantasy lite!” Pretty much take the tone and style of that book and magnify it and you will get this story! There’s simply more of everything: more focus on the intricacies, oddities, and cultures of academia, more complicated and verbose sentence structure and specialized vocabulary, and even more commitment to the epistolary style. In “Emily Wilde,” many times her journal entries would read as a straight narrative. Here, the author is fully invested in telling a story only through letters and supporting documents, so the narrative plays out in a more distanced way.

And I loved all of this! I love authors who can so naturally capture this sort of long-form, “old fashion” style of writing where sentences are long and word choices are elaborate. I also really enjoyed the slow reveals of the many mysteries and secrets at the heart of the story. Not only do we have the remove of learning this story through the more limited form of what letter writers choose to share with one another, but we also are piecing together what happened in the past as the siblings of another pair of characters work to compile the correspondence of two characters who have passed away.

I really enjoyed all the characters we have here, both pairs of writers feeling fully realized and interesting. E, I think, rose to the top simply for how well the author managed to portray a character who lives with high levels of anxiety that affect how she lives her life. In the past, I’ve often found myself frustrated and disappointed by the rather surface level portrayal of characters like these, but the topic is so perfectly explore in E, both honestly depicting her struggles, but also not defining her by this trait. I also really enjoyed Sophy, her younger sister who has her own adventure and must later work through E’s past letters to try to discover what happened to her. Sophy is a much more action-oriented character, and the contrast between them was nice, as well as the loving, strong sisterly relationship we see between them.

I’ll also make a small plug here with regards to the genre of this book. I’ve seen a lot of reviewers calling this fantasy, but I think this is a perfect example of a science fiction novel that doesn’t take place in space. Too often, it feels like readers and marketers think that “science fiction” and “space” are synonymous, but this book perfectly highlights why science fiction needs to be remembered as being a broader category. In almost every way, this book much more closely aligns with the conventions of science fiction over fantasy, especially with its academic focus, which is very scientific in nature. Not only that, but the history of this world and the mysteries we discover all fall in better line with science fiction than fantasy (in many ways, it reminds of the movie “The Abyss.”) This isn’t necessarily a hugely important distinction, but I do think science fiction readers might miss this one due to the fact that it’s being called a fantasy story much of the time. Anyways, there’s my TED talk on that topic!

Overall, I really enjoyed this book! I was surprised to find that it’s the start of the series, and it does end on a mild cliffhanger. But there were so many interesting twists and turns (both with the larger mystery and with a few character turns that really took me by surprise) that I can’t wait to see where things go from here! Readers who enjoy rather long-winded, heavily academic fiction will likely enjoy this one! Also those looking for a lovely slow-burn romance!

Rating 9: Cathrall embraces the full beauty of the epistolary novel, creating a vivid, immersive world and peopling it with characters I’d follow into the darkest depths!
