Children of blood and bone: chapter 2.

Chapter 2 – Zélie
“It’s a diviner tax.” I grip the draped fabric of my pants, still haunted by the guard’s touch. “They came for Mama Agba, too. Probably hitting every home in Ilorin.”
  Tzain presses his fists to his forehead as if he could smash through his own skull. He wants to believe that playing by the monarchy’s rules will keep us safe, but nothing can protect us when those rules are rooted in hate. 

This can be compared to today world with all of the racism, and the unfair treatment of people of colour and how they are under pained and treated extremely different just like how the diviners are treated by everyone else.
