I dont think he lost a life in Sunset, because Brambleclaw kept thinking he had to hurry and save him before he lost a life, and he did save him. Here: http://warriors.wikia.com/wiki/Firestar All the things about him are there. it lists the lives he lost in each book, but it didnt say anything about losing a life under "Sunset", and I dont remember it, so I'm confused
Hmm, that could be right, maybe that's why I didn't remember it in the first place. And I don't have a link to provide, it's in the book. xD He was sort of choking, then became still while Hawk and Bramble were fighting, from what I remember. But I guess he didn't lose one....
