The Drug of Death

After the events of "The Drug of Friendship", the Karas' fate seemed sealed for a glorious future. But a new threat looms on the horizon, and it is just as dangerous, if not more, than the ones they once faced in the past: it involves the future of humanity itself. The Karas will have to re-confront all the enemies they once fought to win in previous adventures, while at the same time running the risk of being finally discovered by the rest of the world. - Based on the series "Os Karas", by Pedro Bandeira, holder of all copyrights and Kara dos Karas
