What a book! Second-world fantasy at it's finest! The world building was intricate and immersive, but blended seamlessly with the plot, so none of the details ever bogged down the story. The characters are immediately engaging, and there's so much tension! I also really enjoyed how the book takes the "girl dressed as a boy to blend in" trope and turns it on its head, giving us instead a moving story of Flora exploring her genderfluidity. The magic system is also really cool! Stellar world-building, amazing characters, and a fast-paced plot. 10/10 would recommend if the phrase "genderfluid pirate" sounds like your jam.

This book is SO GOOD. I wasn't expecting it to be amazing as it is and I'm blown away.
The diversity, the representation, the plot, the characters, everything about this book is 10/10.
I did assume from the cover that this was middle grade, which it is definitely not. This book isn't slow at all and the action starts right away, which I loved. It's fast paced without being rushed and the plot is so engaging, I would being reading for hours and never get bored.
I loved the characters so much. I enjoyed the diversity and representation so much. I can't remember the last time I read a diverse fantasy YA book thatI enjoyed so much.
The writing was wonderful and the concept was fantastic. I honestly have nothing negative to say about this book, I enjoyed it so much. It's been such a long time since I've loved a YA book so much and The Mermaid, the Witch, and the Sea is everything I needed from a YA book and more. I highly recommend picking up a copy.
