Warriors: Stained Shadows (OC Fanfic)

Justice has gone unserved for far too long in the forest. There was a time when ShadowClan was nothing but ice-hearts, and one apprentice suffered. As the apprentice was cast out, he swore that he would set their wrong doings right by delivering vengeance on their kin for seasons to come.
Now a Dark Forest warrior countless seasons later, the tom begins his revenge, delivered through another misguided young tom in ShadowClan. Reedstrike has set his paws on a dark path ages ago, and there's no turning back now. But the pain Berryclaw and Reedstrike have planned for ShadowClan will never compare with what Reedstrike's mate will have to go through. As Reedstrike continues falling down a starless path with no return, as Berryclaw's evil plans only begin, and as Larkounce making great sacrifices on her seek for her affections returned, will she survive the horrible, dark mess she doesn't know she's working so hard to run into?
