To Chase a Prophecy (en Inglés) - Sterling M.Z.

They stole her. They trained her. 

They made their perfect weapon. 

They made their perfect enemy. 

Astra, officially known throughout the base as Project S-001, has been raised to be the premier warrior in Mission Esuvn: master of weapons, brilliant military tactician, the heartless sword of victory. But after eighteen years, her world begins to spiral. She still doesn't understand why her commander says her power over water and ability to self-heal make her a monster, but her trainer says they are her greatest gifts of all.

When Siren, her commander, sends Astra into another trial, she's faced with a crisis-one of loyalty, identity, and wants. Soon, she'll learn that though the base views her as a monster, another realm a portal away knows her to be a savior. Interrea-a world filled with Vismunds who control elements-were sent seven immortal Prophecies to defend them against Siren. Astra is one of them.

With the life Astra once killed to be a part of now the last place she wants to be, she vows to make it to the portal separating the First Realm from Interrea. But Siren doesn't let her weapons go easily, and the destruction that follows Astra into the forest, along with the stranger caught in the cross fire of her escape, will change her mind-and her heart-forever. 

This special edition version of the book includes a bonus chapter from the perspective of the Meastilo king, Ciro.
