I love this series pretty hard. Mercy is such a great combination of strength, courage, and vulnerability and doesn't let her many suitors get in her way.
Yes, she has many suitors it seems. Normally, this would aggravate me. Right now, it feels like it's legitimately explained through the relative dearth of females and the desire to keep things pretty close in the magic community.
I'm sure glad these covers aren't lying around though.
