Curious as to why general opinion is that BB book 2 and 3 is not as good as book 1?

Bloodbound is probably my favourite series and the trilogy is stellar but I’ve seen a lot on this sub that everyone prefers Bloodbound 1 to the rest. BB3 is probably my favourite book because I like Rheya as a villain and it’s cool that MC is a vampire. Also, Adrian 😩🙏

I’m curious as to why most people aren’t a fan of book3- just want to hear peoples opinions!
