We have the ebooks, physical, and audobooks.

They also have a comic, too. Looks like more of them than I thought.

You know, I never noticed the different skulls on the spines. Is their number and fill status meaningful?

I like that the covers themselves have lines from the books and not necessarily just the title. The sleeves are also great. I wonder what book 9's colors are gonna be.

Cool collection! I like the loud coloring. I see the books get longer as the series goes on.
