Planet Atmos: Exordium (Planet Atmos: Exordium #5)

Addy Aker was not born. She was made - engineered on a dead world as a weapon. Now, for the first time in her life, she could be something else. But she'll have to destroy what she was, and the order she left behind isn't finished with her. Old allegiances fracture as Jötun's reach extends further than darkest imaginations could fathom. On Atmos, some debts are paid in blood.
