Spirit Of December summary:

Beyond the mountains, trees, and flowers of our Earth, lies a mythical place better known as The Spirit World. A place which hides our true origins within the seasonal winds of its rainbow-colored skies and fluffy pastel clouds. Long ago, a group known as the Temporas were born with only one purpose, to create the universe. But that was written in stone many centuries ago, unlike today's blue-eyed pair destined to break all despair. Hopefully, twins Ember & Eira are able to complete all the tasks faced before them.
