The Tree on the Hill [EPUB ebook] 

The story is written in first person. It depicts the main character going outside Hampden and finding a special tree. The tree makes him day dream about a big temple in a land with three suns. The temple was half-violet, half-blue. Some shadows attracted him into the inside. He thought he saw three flaming eyes watching him and he shouted twice and the vision was gone.
