This book completely took me by surprise. I requested it because of the title. Sibling relationships are my weakness and I feel like we need more YA books that focus on this.

Sisters of Sword and Song is heavily inspired by Ancient Greece, and as someone who studied Classics in university, this book was everything I could have ever hoped for. It reminded me in many ways of Circe by Madeline Miller. The way this book is written is very reminiscent of the epics and plays that I read in class. There's a formality when it comes to the dialogue that can be a bit jarring, but I think it works well for how this story is told. The gods and their relics, the magic formed through song, the world itself...I loved the attention to detail and the depths this book went to make the world feel so tangible and complete.

The plot had me on the edge of my seat for the first half of this book. After that point, it does become a bit predictable, but I still enjoyed it. I loved seeing the journey that each character goes on, and there are so many good moments between Evadne and her sister Halcyon, as well has Halcyon and Commander Straton.

The romance in this book was something I actually liked. I think it helped that this book is based so much in mythology and written in a way that it mirrors an epic. The romance felt right and flowed well, but it didn't overpower the plot. There was even a moment when Evadne is like "okay, not now" and she never loses sight of her end goal or her sister. I think that was what sold me for this book. I hate when the romance takes the forefront in a book and the characters start to completely ignore everything else. That being said, the last 10% of the book does become a lot more romance-heavy. But since it was only the last couple chapters, I didn't mind it so much.

Overall, for a standalone, this book was so good! And I'm definitely going to be checking out Rebecca's other books one day!
