I don't hate Zoey, she I understand and can sympathise with.
Heath's dead (mostly), so I'll move on from that subject.
Neferet? Too obvious, I'm supposed to hate her, which I do. The press conference was a stroke of brilliance, involving the humans finally, but her plans have been failing more times than they succeed and now she's getting boring. I can understand why the white bull isn't impressed anymore.
Erik, maybe? Honestly liking how's he's moved to the background. Love that he's miserable as a Tracker, and that Shaylin isn't taking too much of his nonsense.
I think it's still too early for me to judge Erin, so not her either.
I think I'll say Stark, he's overprotective, and often the one questioning Zoey's judgements which is no good in building her confidence.
