Amazon.com description: Product Description: Deep in the dense Colombian jungle a mysterious emerald has been plundered by an odd band of backstabbing pirates. An unlikely character, Sara Gomez, is thrust into the action. With fang-like teeth and inexplicable nocturnal walks, she is no longer safe in her vampire-frenzied community. But alas, in 1741 the high seas are just as dangerous as lingering with landlubbers. An easy Spanish reader containing just 240 new vocabulary words and many English-Spanish cognates, this book belongs to the genre of Language Learner Literature.
