Saphira's Unlocked World

Saphira, a fifteen-year-old girl, is a fighter, traveler, scavenger, and friend. She lives an odd life in the Unlocked World, on her own with the protection of her sword, dagger, and bow and arrows.
Things, the skeleton-like creatures that are always after her, haunt her dreams and force her to live in constant fear.
One life-altering day, Saphira stumbles upon Zack and Alice, twins from earth who fell through the portal.
