We are part of a group of librarian friends who have had an ongoing book club running for the last several years. Each “season” (we’re nerds) we pick a theme and each of us chooses a book within that theme for us all to read. Re-visiting some of our past themes, we’re once again pulling random words from a hat and finding a book that matches the prompts. For this blog, we will post a joint review of each book we read for book club. We’ll also post the next book coming up in book club. So feel free to read along with us or use our book selections and questions in your own book club!

Book Description: In Coney Island, true love rises to the surface. With lush illustrations and buoyant prose, Venessa Vida Kelley forges an unforgettable New York fairytale.
Benigno “Benny” Caldera knows an orphaned Boricua blacksmith in 1910s New York City can’t call himself an artist. But the ironwork tank he creates for famed Coney Island playground, Luna Park, astounds the eccentric sideshow proprietor who commissioned it. He invites Benny to join the show’s eclectic cast and share in their shocking secret: the tank will cage their newest exhibit, a live merman stolen from the salty banks of the East River.
More than a mythic marvel, Benny soon comes to know the merman Río as a kindred spirit, wise and more compassionate than any human he’s ever met. Despite their different worlds, what begins as a friendship of necessity deepens to love, leading Benny’s heart into uncharted waters where he can no longer ignore the agonizing truth of Río’s captivity—and his own.
Releasing Río could mean losing his found family, his new home, and his soulmate forever. Yet Benny’s courageous choice may just reveal a love strong enough to free them both.
Kate’s Thoughts
I’ve been to Coney Island a few times in my life, having strolled on the beach and walked through Luna Park. There’s something special about Coney, and there is something that just feels so profoundly ‘New York City’ about it. When our book club chose “When the Tides Held the Moon” by Venessa Vida Kelley I was already on board because of a queer romance between a blacksmith and a merman, but the 1910s Coney Island setting made it all the more tantalizing. It just feels like a New York story.
I loved so much about this book. The setting is the first thing, as there is such a romantic and fairy tale aspect to 1910s Coney Island, and a circus that is teeming with found family potential. The idea of a ‘freak show’ having people living on the edges of society and finding connection and companionship with one another is always a story that’s going to hit me in the feels, and Kelley adds in the fantasy element of merman Rió and has even more of a punch. I loved the way that Benny finds love and companionship not just with Rió, but also with a group of people who feel Othered in ways that, while not being fully the same, resonate for Benny, who is a fish out of water in his own way thanks to coming to New York from Puerto Rico and dealing with racism and xenophobia. The way that he connects with people who also feel on the outside for various reasons, be it race, sexuality, gender expression, and other things, was a genuinely heartwarming aspect of this book.
I also really loved the romance between Rió and Benny, with the slow build up of their love story really capturing the tenderness and beauty of their connection. It really reminded me of “The Shape of Water” (and I know that isn’t a unique comparison, but that’s because it’s APT). We see it through both of their eyes to some degree, as while Benny has most of the POV we do get some interspersed chapters of Rió’s thoughts and feelings as well. I liked how they challenged each other and lifted each other up, also connecting because of feeling so alone in the world. It’s the kind of aching romance that will just capture a reader and sweep them away, and it was one of the most effective romances I’ve connected to in recent memory (hilariously enough, another one like this was in “Trad Wife” and it also involved a human and an otherworldly being). Both Benny and Rió bring such passion and joy to the relationship as it unfolds and the circumstances become all the more heightened due to Rió’s captivity and issues that Benny is having with his own role in that. I was fully invested.
I loved “When the Tides Held the Moon”. It’s dreamy and romantic and touching and buoyant. I can’t recommend it enough.
Serena’s Thoughts
While I don’t have as many connections to New York City as Kate (I’ve been once for about 24 hours, much of which was spent bar hopping with my sister because it was pouring rain, the ferry to the Statue of Liberty was closed due to hurricane damage, and we were constantly waiting to meet up with an overly busy friend who was delayed), it’s still a city that has a clear “presence,” for lack of a better word. And this book followed one of my favorite storylines for fantasy fiction, where the author manages to merge the fantastical right alongside the very real, very human world that we know. So on one hand, yes, you have a love story featuring a merman. But you also have a love letter to a very specific time and place, New York City in 1910s. This was especially appealing to me as I also enjoy historical fiction, and this is a time period and location (somehow I don’t read many historical fiction pieces that take place in the U.S.) that I was less familiar with.
The writing was also lovely. I’m a sucker for lyrical, whimsical storytelling and this one had it in spades. The style of writing only accentuated the primary themes of the story, those of love, found family, and what makes up a home. There were many lovely passages that had me stopping to re-read and truly appreciate the author’s skill.
The story is definitely on the slower side, which I think worked well, especially with the emphasis on the atmospheric nature of the storytelling and the slow burn romance that developed between our main characters. But for readers who are looking for a faster pace, this probably isn’t that. I’d also want to note that while “monster romance” is a big subgenre in romantasy currently, this doesn’t really fall into the same category. The love story here was much more intimate in the emotional sense and all the more beautiful for it.
Overall, I really enjoyed this one! I had had it on my TBR for a while now, but hadn’t gotten around to prioritizing it. So yet another win for bookclub!
Kate’s Rating 9: A lovely and deeply romantic story about love, belonging, found family, and connection with a dreamy backdrop of 1910s Coney Island. I loved this book.
Serena’s Rating 9: Atmospheric and lyrical, this is a perfect blending of fantasy, historical fiction, and romance! Sure to be a hit with a variety of readers!
