Warriors Dark Wonderland: The Broken Warrior

Book 1
The six clans are in danger. There always seemed to be a darkness calling the warriors, one by one. The darkness only has one task, to overcome the warriors. But now the time has come for 5 apprentices to take their place in MoonClan. But darkness is regaining control every single day. The 5 apprentices, Darkpaw, Graypaw, Bramblepaw, HawkPaw, And RainPaw, will venture into the darkness and discover its mysteries. But StarClan fears something, sometimes to defeat darkness, is with more darkness. And this darkness will rest upon the most battle-hungriest warrior in MoonClan, one of the apprentices' mentor, MoonHeart, in order to get revenge on her kit-hood.

And the 4 apprentices will have to face betrayal within the clans.
