Green-Eyed Monster (Nancy Drew, Girl Detective: Model Mystery Trilogy, Book 1)

George, Bess, and I were so excited when we won an amazing vacation at an eco-resort in Costa Rica. Fun, sun, surf -- all in the name of ecology and helping to keep our planet clean. But, as always, dirty business seems to follow me wherever I go, and this resort isn't as spic 'n' span as we originally thought.

After a string of increasingly dangerous "accidents," it seems that there is a jealous predator staying at the resort, making trouble for the management and the guests. Against the urging of my friends, I know that I need to take this case and get to the bottom of it before our entire week at Casa Verde is ruined -- or worse. Can I uncover who is sabotaging the press tour before it's too late? Or will our vacation come to an unhappy end?
