I promised to take care of him until he didn't need me anymore. I made a mistake. I was twenty-two. Just a broke artist with a pair of scissors and a flashlight, hired to be his nanny. I did my best. I built him a sky out of cardboard boxes. I held his hand when the thunder was too loud. I taught him that he didn't have to be alone in the dark. But children grow up. And Silas Vane grew up... different. As the years passed, I started noticing things I couldn't explain. My dates getting cancelled. My debts mysteriously paid off. The feeling of eyes watching me while I slept. I thought I was raising a lonely boy. I didn't realize I was becoming the center of a dangerous obsession. Now, he is a man. A genius who controls everything around him. And he has finally solved the only equation that matters: How to keep me forever.
