Onyx storm is horrible

Ughhhh I'm reading onyx storm since it was published and I cannot manage to end this book.... ITS SO TERRIBLE?! I really liked FW and loved IF but OS???? 1. There is not plot. I don't understand what's going on 2. Violet = Mary Sue 3. What happened to Xaden???? He doesn't have a personality anymore, only a Violet obsession... 4.THEIR LOVE STORY IS SOO CRINGE UGHHHH 5. I want to hit Ridoc for making jokes 24/7 6. Flat characters, Halden just shut the fuck up 7. WHY IS THE PACING SO SLOW? 8. I loved the idea of Xaden being Venin but it was so badly written and I thought he would become evil or something like that 9. The fact that Xaden would choose Violet over Tyrrendor but he only knows her for idk 1-2 years yup. This is the heir of Tyrrendor 10. Literally. No. Plot
