Of course, I’m not going to murder her in the night. I need my laptop back first. That’s the whole point of making friends with Emily Harper, author of the hugely successful novel Diary of an Octopus. So I could get into her apartment and take back what’s mine.

She doesn’t realize the laptop she found—and took—from a busy airport almost two years ago was mine. I don’t care about the laptop, just what's on it: my diary.

When Ellie tells me she has a new boyfriend, I am absolutely thrilled and can’t wait to meet him. She finally seems so happy and in love. But there’s a catch. Ellie has never met him in person. In fact, he doesn’t even live in the same country. Our home is in England, but Daryl is in Los Angeles.
