None of the warriors books are 'real' if you mean that you think the cats do exist, then no. But the book, Sunrise is real.
Yes there are a few battles in warriors sunrise!
Hollyleaf.
As of the warriors book Sunrise, Hazeltail has not yet died.
uh
He doesn't die.
Look on the warriors website or publishers.
Sunrise is the sixth book in Warriors:Power Of Three. Jayfeather, Hollyleaf, and Lionblaze try to find out who their real parent's are, and ThunderClan thinks that the loner cat Sol murdered one of the ThunderClan warriors, Ashfur, and some of them set out to find him. One of the best books in the Warriors series in my opinion, but it is literally brand new as of April 21, 2009.
leafpool and crowfeather

Yes,it was published April 21st,2009.
It was suppose to come out on April 21.
In the book "Sunrise" of the Warriors series, Hollyleaf dies after being trapped in a tunnel collapse. She sacrifices herself to save Ivypool and Dovepaw.
