Shadow of a Slave

In the Known Kingdoms, Twins are killed at birth.  Twins harness energy in an unpredictable and dangerous way.  Twins almost destroyed the world.  Ash and Rae have always claimed that he is a year older to hide themselves from the ruthless Faceless Monks.  An order who's apparent benevolent mission to keep the world safe, is a mask for nefarious intentions.  Energy can't be created or destroyed... but it can be harnessed...  When Ash and Rae's secret is discovered, Rae is taken by the monks. Ash must learn to harness his natural ability to manipulate the energy of his world to save her.  Two rules must always be observed. Two rules everyone knows.  Do not use energy from the living.  Do not reanimate the dead.  Ash will do anything to get Rae back...even breaking their sacred laws.
