Ravenpaw's Sacrifice

This AU takes place when Firestar, Graystripe, and Ravenpaw are trying to escape RiverClan/TigerClan territory to save Mistyfoot, Featherpaw, and Stormpaw from the threat of being killed for their half-Clan blood. In canon, a ThunderClan patrol consisting of Sandstorm, Cloudtail, and Thornclaw arrives just in time to help hold off the advancing ShadowClan warriors at the stepping-stones, allowing the three TigerClan prisoners to escape into ThunderClan and be brought in to be safe from anymore threats. But what if the ThunderClan was too late to come, or didn't come at all?

Why Ravenpaw ran away from the Clans in the first place is the very thing that happens.
