Treebus and the Triplets

While visiting the forest, Gracie meets Treebus, guardian of the forest. He's an Earth angel who dwells in a hidden garden and walks the earth, continually protecting it.
The youngest of triplets, she develops a close relationship with Treebus as he teaches her about the miracles of Earth's creation and continued existence. A dark angel-appropriately named Darkness-uses his deceitful wiles to convince a large part of humankind that the planet will soon be destroyed by their own negligence. Gracie and Treebus form an alliance to defeat Darkness and convince humankind that Earth is not doomed.
