SECRETS. SCANDALS. ESP. We weren't always like this. We used to be average New York City high school sophomores. Until our homeroom went for flu shots. We were prepared for some side effects. Maybe a headache. Maybe a sore arm. We definitely didn't expect to get telepathic powers. But suddenly we could hear what everyone was thinking. Our friends. Our parents. Our crushes. Now we all know that Tess is in love with her best friend, Teddy. That Mackenzie cheated on Cooper. That, um, Nurse Carmichael used to be a stripper. Since we've kept our freakish skill a secret, we can sit next to the class brainiac and ace our tests. We can dump our boyfriends right before they dump us. We know what our friends really think of our jeans, our breath, our new bangs. We always know what's coming. Some of us will thrive. Some of us will crack. None of us will ever be the same. So stop obsessing about your ex. We're always listening.

What's worse than having telepathy in high school? Having telepathy in high school, and then losing it. When class 10B got their flu shots and developed the unexpected side effect of telepathy, it seemed like the worse thing ever. But two years later, they've got used to their powers. They've even come to like them. And as they prepare to leave school, they're all making exciting plans - plans that involve them being Espies. So when one by one they suddenly begin to lose their powers, they know they can't let it happen. Can they save their telepathy before it's too late? Or will they have to learn how to survive without them once again?
