Spoilers!!! If you have not read Warriors Sunrise, do not answer!!!?

Do you think Hollyleaf is dead? I don't think so, because when the tunnels collapsed and she was inside, it said Jayfeather only imagined her being crushed. And, there was no painful yowl. Besides, her death came to quickly. Also, the Erins announced that there was going to be a female villian in the next series (Omen of the Stars or The Fourth Apprentice, I'm not sure.) So, do you think Hollyleaf is dead?
