Jackson ("Jax") Day is about to discover a truth that will derail his destiny: his world of power and privilege never should have been. With "virtual time travel," people of the future tried to redeem a tragic past by assassinating history's most notorious genocidal dictator. Disaster ensued.

With the help of a resistance movement known as Scion, Jax begins to piece together clues about a new destiny he could never have imagined...
