Warriors fire and ice By Erin Hunter

Fireheart is a ThunderClan warrior cat now, but danger still lurks in the forest - and possibly closer than he thinks. With the chill of winter setting in, the cats of rival RiverClan are growing restless, while WindClan turns weak and faces threats from all sides.

As tensions build up to an explosive climax, Fireheart faces not only imminent battle, but betrayal from within his own Clan.
