She left her family. She left everything. It was only when the doors locked behind her that she realized Carlisle had been watching her long before that first night at the art gallery.

Her name was Cathedra. Leave her last name blank, if you will. Where normal people would read, "And they lived happily ever after," at the end of every fairy tale story, she could see something else. Three different things. Three words: Lies, lies, lies. A picture that moves. And a plea: Please tell them the truth. All her life she dedicated herself to becoming a writer and telling the world what was being shown in that moving picture. To expose the lies in the fairy tales everyone in the world has come to know. No one believed her. No one ever did. She was branded as a liar, a freak with too much imagination, and an orphan who only told tall tales to get attention. She was shunned away by society. Loveless. Friendless. As she wrote "The End" to her novels that contained all she knew about the truth inside the fairy tale novels she wrote, she also decided to end her pathetic life and be free from all the burdens she had to bear alone. Instead of dying, she found herself blessed with a second life inside the fairy tale novels she wrote, and living the life she wished she had with the characters she considered as the only friends she had in the world she left behind. Cathedra was happy until she realized that an ominous presence lurks within her stories. One that wanted to kill her to silence the only one who knew the truth.

For three years, I was the only one allowed inside my husband, Matthew Carter's, secret room on the top floor. Until that day—when I walked in and found his young assistant there. "Matthew asked me to get things ready for his dinner party," she said, all confidence and no shame. I smiled. It turned out this was what it felt like to have my privileges as his wife trampled on. Fine. If the rules of the game had changed, then I would show everyone who the real player was. One by one, I dismantled the Carter family's most prized projects. That was when Matthew finally panicked. He demanded, "Why? We're husband and wife!" "Exactly," I said, tossing the divorce papers onto his desk. "And that's why betrayal comes with a steeper price, doesn't it?"
