This addition to the series adds quite a lot of context to the house of Slaughter, the lore for how monsters are made, and gave space for James's character development as he he takes steps towards learning to forgive himself.

This would be a satisfying point at which to finish the series, so I'm looking forward to what comes next and how things change for Erica, James, and Bian. I'm curious if Tommy's storyline continues. The cover art with Tommy holding a shadow of Sophie, makes it look like he either has or will capture his own monster and turn it into a kind face with which to grieve.
