An American college student finds herself caught in an international crime spree in this classic YA suspense novel by a New York Times -bestselling author.

Maura Kelly longs for some excitement in Mexico City before she heads back to classes. She enjoys swimming in the blue waters of Acapulco, but the boys she encounters are rather dull. Luis, on the other hand, is charming, suave, and confident. Maura is thrilled, but her roommate, Lin Prescott, is suspicious of Luis's confidence...

Soon Maura is on the run and sending cryptic messages to Lin. Neither girl is certain if they can trust anyone, but if they can meet up in Veracruz, perhaps they can figure out what's going on. And perhaps the roommates have a chance at eluding ruthless criminals who will do anything to protect their secret...
