Great world building, but not much happening in the world. The premise hooked me

(the main character can see ghouls)

, but there characters didn't have much depth (I wasn't really impacted when

Matthew died

. I wish there was more insight into Olivia's feelings at the end, how she feels about moving forward and knowing her predicament/fate

wasting away like Matthew

. Or maybe she won't, because of her

dad and being partially from the other world?
