The Obelisk Gate is the second in a trilogy by N.K. Jemisin called the Broken Earth Series. It is about a world missing its moon and in its place has gotten only turmoil and destruction. In this world, there are humans with the power to manipulate the energies of the earth and tap into its gravity and force. These Roggas or Orogenes, as they are known, have enemies too. Many many enemies. They are feared by most and hunted by others. Even the earth wants them dead, but the Earth wants everyone dead and it just might get what it wants.
