The Two Sisters of Marmora: A Voltron Legendary Defender Fanfiction

Amber was found clinging on to life after the pod crash that killed her birth parents. Thank goodness the Blade of Marmora saw a great future ahead of her, and trained her as a warrior. After struggling to survive the brutal training regime, Amber is placed on a mission far away from the headquarters where she grew up, and far away from her foster sister Kayla. Doing recon on a Galra stronghold should be easy, but there's tension in the air about the change in Galran leadership. And once Amber arrives, she realizes she's not the only spy in town...

All that Kayla knows about her birth mother is that she was a member of the Blade of Marmora. Having been raised by Amber for the past ten years, her heart breaks at the thought of losing someone else she loves. However, shortly after her sister leaves, Kayla gets into huge trouble on a mission of her own and barely escapes. Indebted to those who saved her life, Kayla finds herself traveling farther than she ever planned and trying to hide from her own fears...

This is the story of two spies who might just shake up the rebel groups like they're shaking a snowglobe.
