Warriors: Fire and Ice, by Erin Hunter

This book was awesome!  It is about how Fireheart and Graystripe are trying to bring Wind Clan back after they were chased out by Brokenstar.  After that, Fireheart and his clan battle River Clan and Shadow Clan for attacking Wind Clan.  Brokenstar and some rogues attack Thunder Clan but Firestar is there to stop it.

I liked this book because it had lots of action.

Two other books I would recommend are:

Warriors: Into the Wild AND Framed.
