Defiance (The Courier's Daughter Trilogy, #1)

Rachel’s world is confined to the protective walls around her city. Beyond them are violent wanderers, extreme terrain, and a danger straight out of legend: a beast called the Cursed One that devastates everything in its path.

When Rachel’s father goes missing, she is desperate to search for him. But her attempts to flee the city bring her to the attention of its overbearing ruler. His efforts to control her make the world within the walls seem as dangerous as that outside.

Her only chance at escape is Logan. Once her father’s apprentice, and now her only protector, he feels that helping her might mean losing her completely. But if he can put his feelings aside, they might be able to save more than Rachel’s father. They might be able to break down the walls, and set their people free.
