• It was based in Greece or Egypt - I think Greece, most probably, at least that’s what the vibe was, from the foreign-sounding names
  • The civilization is decently advanced, as in, they have figured out sanitation and trading, and stuff like that
  • The plot revolved around uncovering the truth about a mysterious disease, most probably a certain type of plague
  • The protagonist is a teen, I don’t remember if he’s a slave or a peasant, or from a middle-class society. I’m not even sure if it’s a “he”, maybe it was a “she”? Or maybe I’m mixing the protagonist with another female character in the novel?
  • It is not a time-travel novel - no one from the modern time is involved
  • There was non-graphic mentions of murder, and something about conspiracy in the ancient society
  • There is also a slave side-character, who is a teen
  • The book had the vibe of Nancy Drew, Famous Five or the Secret Seven but in an ancient civilization
