Warriors: Vision of Shadows: The Apprentice's Quest by Erin Hunter

I actually like the idea of Needletail tagging along the ThunderClan cats, because their mission was to find SkyClan. Why can't anyone--anycat know about SkyClan? I mean, I get that SkyClan's been droven out by all four Clans at a Gatherings, and after the Clans were ashamed, but I think if all cats from every Clan should've gone, 'cause everycat should know nothing will ever NEVER, be the same when the truth's out, or if someone discovers the truth. SkyClan is just a Clan like any other Clan, but droven out countless moons ago.
