I'm at 75% read on this book and I think it's going to be a never finished book for me. I loved Fourth Wing so I was excited to read the sequel. Violet's character changed from the unpopular underdog, turned respected warrior in FW to an insufferable, insecure, self-depreciating, jealous pain in the ass in IF. The relationship between her and Xaden is toxic and I'm so tired of them both being 'upset' with some irrelevant secret they have kept from each other. The sudden appearance of Brennan, who had played dead for 6 years, was totally brushed aside and should have been a more in-depth story line. I'm at the point now where I simply don't care how it ends.
