In the midst of working on the book itself (which I can't share yet), I am also at work on the cover (which I can share, and so here it is):
This isn't final, and could change drastically, but I'm happy so far. I may hate it tomorrow…or I may not.
If you see any glaring errors with light and/or shadow, please let me know. The text is particularly not-final, since the only program that can alter the kerning as needed lives on an old, packed away computer.

Got a great comment that the terrain resembled sand, and so I adjusted things a bit. (It is meant to be snow.)
UPDATE: June 12, 2015
Decided it was still reading a bit sandy-brown, thanks to the warm yellow of the setting sun rather than a less saturated, wintery one.
UPDATE: June 13, 2015
Got some comments about the hue and lightness (purple and dark).
