It's a story book.
It starts with young Oliver Graves and his father, attending a lonely funeral for his mother. Once they finish their prayers they return home and Oliver is laid to sleep. Near the stroke of midnight Oliver wakes to see a cloaked girl in the fields, picking flowers. He follows her up the hill all the way to the cliffside. After nearly falling into the sea he makes his way up and is spotted by the girl. She tells him that he must have had a great tragedy to see him. He tells her of his mother, and so she offers him a capricorn scale to make him feel better. Suddenly the winds carried the storms to frightening strengths, and the crescent moon becomes unnaturally visible. She commands him to leave but he refuses stating he is old enough to see. But she tells him "Some things nobody is old enough to see" but he stands unmoved. Eventually he agrees to hide behind a tree. She runs to the edge of the cliff and uncloaks, bearing a beautiful flash of light that shoots to the moon. Swirls flow in the clouds above and petals fall from her skin, getting carried in the winds and in one last bright flash, disappears, leaving the moon full.
Much of the rest of the book is covered in ink stains, making it impossible to read anymore. But at the end there's a few pages on symbolism of the moon and earth.
(Btw the story is from someone else. They just made a movie and my family loved it. Btwbtw the other books are based off their albums. Btwbtwbtw this was a cheap way to basically advertise their movie, because they like their followers getting more people to hear them)
