The Daughters of Ys

Two sisters, in a mythical kingdom, are daughter of a witch? They control the sea, bringing prosperity to the kingdom and showing off great magical abilities (like controlling sea monsters and having underwater ballrooms). One sister throws it all away and lives like a pauper in the woods, the other sister pays the price for all of the magic. When she make a decision to not pay the price one night, the thing controlling all of the magic shows up looking for recompence. The father is a total a-hole in this story.

Note to self: I knew going in this would be a weird one. I read it over a week. I'd like to say that I loved it, but I didn't and I have a feeling that has everything to do with the format. I tried reading it online and every time I loaded the book, it crashed the app (on my Kindle). I ended up reading it on my phone. I highly suspect I would have enjoyed it more if I had been reading a physical copy.
The story is unique, and the art is exceptional. I just couldn't stand reading it on a small screen where I had to zoom in on every panel to read the text.
So, to be fair, I will find a physical copy, reread it and update this review later.
