POPSUGAR: At the risk of sounding like a total freak, I read your entire book in one night. I just could not put it down.
Caroline Kepnes: I love that. I love that feeling!
PS: It sounds like your experience writing it was kind of like that, too.
CK: Yes. I think my thumb is permanently damaged. I would literally have to stop writing because my fingers were bent. I would get in the car, and I would be at a stoplight, writing in my phone. It just wouldn’t shut up, in the best way. The first draft I wrote very quickly, within a few months. I wrote the first 40 pages over a few weeks, and then I wrote the rest of the book in a few months. I would just wake up wild-eyed — that’s assuming I was able to sleep — and then drive like a maniac to a coffee shop and write all day.
