Unthinkable [EPUB ebook] 

Omar Phillips is Bridgewater High’s favorite local teen author. His Facebook fans can’t wait for his next horror story. But lately Omar’s imagination has turned against him. Horrifying visions of death and destruction come over him with wide-screen intensity. The only way to stop the visions is to write them down. Until they start coming true… Enter Sophie Minax, the mysterious Goth girl who’s been following Omar at school. "I’m one of you, " Sophie says. She tells Omar how to end the visions-but the only thing worse than Sophie’s cure may be what happens if he ignores it.
