Death's Daughter v1 isn't available on Kobo
It's not even available for pre-order, but oddly, vol2 is showing up their system.
If this isn't the right forum to post this in, please delete.
Being hard to find might have something to do with Kobo erroneously naming the illustrator as the author of the first volume?
I went to kobo.com, searched for "death's daughter," and it's the 3rd item in the search results for me.
