The Demon's Queen by Katee Robert

So I just finished this book by Katee Robert and I'm a little disappointed ngl. That was the only book of the series I've been looking forward to but I guess my expectations were too high. I've also found out that this author is just not for me. One thing that I really didn't like was that while the FMC already knew the MMC she was still having sex with other people. And I'm also not a fan of daddy kinks but I felt like in this book it didn't even fit and felt out of place. I hate that the dude made her sign a life long contract and I also didn't like that the "bad guy" comes to challenge the MMC instead of him going to find him. Idk I just got the impression that he was never gonna do anything about the guy. I also didn't like that the FMC immediately went back to the MMC after he finally let her go. This was my fourth book (novella?) by this author and I don't think she is for me
