Marie, a journalism major, cofounded the Blackbone collective last year with an Italian reporter and Leo, a hacker her age. Together, the three foiled Luca Snyder's scheme to sell a "green" phone whose materials were in fact inequitably extracted from African mines. Next , Blackbone investigated the fast fashion industry, especially in Vietnam. In Green Traffic, Marie studies abroad in Brazil, where she meets Céya, a native whose family is threatened by deforestation, and Joaquin, the son of rich land owners. Unbeknownst to her, Marie has landed right in the middle of a political plot orchestrated by Luca Snyder.
