Book Three: The Path to Tartarus

The third book in the series, "Highschool Project: The Path to Tartarus," in which Afeus Clover, a God-Slayer, attempts to conquer Heaven and Hell through the usage of monsters that come from Tartarus.

Set in the year 2021, the book begins when Zane Jackson, the main protagonist, is visited by the highly-intelligent Afeus, who informs him that he's taken his friend, Ruben Brown, as a hostage.
