Callie was found in a room in which she'd covered the walls with writing: "I KILLED HIM," scrawled over a thousand times. She didn't, and doesn't, remember writing it, or why, or anything about the 36 hours before her discovery. Her preacher father and the other girl, Hannah, are still missing, a year later, And Callie's graphomania is getting worse. She blacks out while scribbling in her notebooks, phrases that might be clues if only they made sense. But the memories are starting to come back. 
 Didn't love this. The mental-health issues didn't ring at all true, and I never got the sense of urgency from the descriptions of it. I had some trouble knowing when we were in the climax as opposed to a flashback--things seemed to shift gears quickly through the whole book. 
 Subplots with Boys were distracting and not that interesting, but the parts with John made sense.
