SEQUEL TO FLIRTATION FORMULA. Emily Fields and Alison Dilaurentis are happy. Anyone who sees them knows this, and they know it. Their lives couldn't be simpler, (or more boring if you ask Emily) and they couldn't wish for anything else. But when they find out that their friends have got themselves into a sticky situation, involving people too dangerous to mention in public, Emily wishes that she hadn't hoped for more in their life. This was gonna be one hell of a year.
