This, the second book in the Warriors series, continues the saga of Fireheart, an orange cat who escaped his human home, joined ThunderClan, one of four clans of feral cats, and became a warrior. Accepted by most but still disliked by some,(Tigerclaw, Longtail, and Dustpaw) Fireheart and his friend Graystripe are sent on a mission by Bluestar, the Clan leader, to find WindClan, who were driven out by the hostile ShadowClan. Once they return(I won't say what happens)things begin to get worse in camp. On their way back to their Clan, the two warriors get into a battle with RiverClan, and a cat is killed when he is thrown over a cliff by accident. Needless to say, RiverClan is not happy. As the plot goes on, trouble stews with sickness in camp, Fireheart's first apprentice, Graystripe's growing love for a RiverClan cat, and Fireheart's discovery of a very familiar cat. When he brings home a white kit, he is ridiculed even more. Failing to persuade Graystripe to stop seeing the RiverClan cat, the two friends' closeness begins to deteriorate. But when rogue cats attack the camp, with Fireheart the only warrior, and soon afterwards a joint attack on WindClan by Shadow- and RiverClan, Fireheart discovers that he cannot trust everyone.
I quite enjoyed Fire and Ice, and have only one complaint. I wish to point out that I disapprove of Erin Hunter implying that all lost cats could make their way in a colony of feral cats. There is little to no chance of a cat finding a colony, much less being accepted. However, that sad fact takes away none of the enjoyment of a good story, providing you understand it's fiction. I don't think that's worth taking away a star, though. That being said, I am looking forward to the next books, Forest of Secrets, Rising Storm, and hopeful sequels.
