It's not the knowledge she has, it's the way she comes across as if everyone should agree with her, because. Perhaps that just how it comes across to me, and not how she was written. I'm just not a big fan of novel Ezri.
I think it's mostly you to be honest; the only time she's come across poorly to me was at the start of one of This Gray Spirit, but I felt like that was just Jarman not having a handle on the character because she got better throughout the book.
I'm really excited for this book. Love Una McCormack's writing and any story with Dax and the Aventine
is must-read for me!
