I'm really, really fond of this series. It definitely deserves to be more well known. 
 First, I'm always partial to a flawed female protagonist, and Mare fits the bill pretty well! The story also holds together, and the fluid writing style is quite efficient. It's hard to fully predict what comes next, and I also love how the characters evolve, and how they deal with trauma and PTSD. 
 Looking forward to the next book!
