Those are the two comics compilations that are available at the moment.
I've updated the pastebin which I posted there: >>113927028
There's a third comics compilation coming in June plus a bunch of other books that I have in my sights, so maybe save the pastebin for when I upload them, I'll try to post them here as well but I doubt Frozen threads will be a thing by the time some of these books release.
These are the books that I'm aware of and am interested in:
Disney Frozen (Graphic Novel Retelling) coming April 7.
Frozen Adventures: Ice and Magic coming June 9.
Frozen 2: Bruni's Big Adventure coming July 28.
Frozen 2: Dangerous Secrets: The Story of Iduna and Agnarr coming November 3.
If you know of any other upcoming Frozen books please let me know.
