The Perfect Escape (Nancy Drew) by Carolyn Keene

This time, I may be in way over my head. What started out as a simple undercover mission at a beauty pageant in New York City has turned into complete chaos! The pageant's sponsor, Pretty Face Cosmetics, knows that I've uncovered a big secret about their product, and now I'm in serious trouble. They want to keep me quiet - no matter what it takes.

Now I'm being held hostage by two supercreepy bad guys, without a phone, and worse, without my friends! I know that Bess and George are doing everything they can to find me, but time is running out. I have to figure out a way to get back to that pageant so I can reveal Pretty Face's secret...before it's too late for the next Miss Pretty Face, and millions of other girls!
