But even though the cats are now safe, the trouble is not over. Squirrelpaw, given her warrior name Squirrelflight, does not trust Brambleclaw because he is friends with his half-brother Hawkfrost, son of Tigerstar and a rogue called Sasha. Leafpaw, now known as Leafpool, falls in love with Crowpaw, now known as Crowfeather. As the cats fight and fall in love, lots of badgers attack ThunderClan, making Leafpool make the choice to give up Crowfeather. It also results in Brambleclaw and Squirrelflight realizing how much they mean to each other. In "Sunset," Hawkfrost wants to kill Firestar so that Brambleclaw can become leader. Brambleclaw realizes that he is more loyal to Firestar than to his half-brother, and he kills Hawkfrost to save his leader.
