The Part 3 cover is surprisingly basic, though still a very nice image overall. It just reveals nothing about the story at all. There does seem to be a bridge in the background between the two ice peaks, which may speak to some form of Southern Tribe becoming modernised plot.
The Part 2 cover for me is the best of the 3. The structure in the background that for me is hinting at some form of oil drilling type thing may hint at the plot and Hakoda being on the cover is great to see.
Both covers now feature Toph, which is interesting in that she has never been to either of the water tribes having joined the group after Book 1 Water. So it will be interesting to see how they go about showing her earthbending in such icy terrain and in general what her involvement will be in the story.
Thoughts on the covers and what they may hint at for the plot?
