A vector of venom infects Antonio, a typical Panamanian teenager, with an illness that has far-reaching consequences. He is carried away from home and transported back in time to the early 1900s, where he unknowingly joins his grandfather on the construction of the Panama Canal. Will Antonio escape from the past and survive the consequences of working on one of the most dangerous construction sites in history?

This Comprehension-based™ reader, ‘Vector’, strategically weaves high-level language structures into a compelling story, based on high-frequency vocabulary. Even upper-level language students need repeated exposure to language structures in order to acquire them, and Fluency Matters’ intermediate readers maintain a high frequency factor of high-level language structures, thus helping learners progress beyond typical proficiency levels.
