I did the best I can, but the order might not be completely accurate
He loses his first life in the battle between Lionclan and Bloodclan in the Darkest Hour
Yes, he died in The Last Hope.
No. I agree with the first paragraph(original person) but not the second. He doesn't lose his last life. He loses ONE life outof NINE. After Starclan takes one life away, he wakes up in the middle of the battle.
Nobody knows which book Firestar will lose his last life in, although many think it will happen sometime in the fourth series. And if it will it will probably be in either the first, second, or last book.Erin hunter has said that they have finished making his death scene and she is only on the third book: Night Whisperers.
Lionheart
It's rumored to be during a big battle as he saves someone.
yes he loses a life when hawkfrost tries to kill him for his brohter to have power
There is much speculation about how Firestar will die. I think he will die by Tigerstar killing him in the final battle with the Place of No Stars cats.
Not yet. he will lose his final life in the last book of Omen of the Stars.
Yes, in "The Darkest Hour," Firestar loses one of his nine lives in a fight against Bone and his rogues in what is referred to as the "fox trap" at Fourtrees.
As of now, Firestar has not lost his eighth life.
Either The Forgotten Warrior or The Last Hope
