Well, to start I have read all the books and I'm starting Forgotten Warrior. I type about spoilers and other warriors stuff. First there is more then one Erin Hunter there about 4. Also the movie everyone is talking about, the Erins haven't say anything about it so no movie yet. On YouTube there are the best trailers and other stuff.
Ok spoilers~ there are some things that are super.

Jayfeather, Lionblaze, HollyLeaf are Leafpool and Crowfeather's kits. HollyLeaf tells everyone at the gathering.
Brambleclaw and Squirrelflight are no longer mates.
HollyLeaf killed Ashfur then ran into the tunnels.
HollyLeaf isnt one of the three but I think is the fourth. ((will make sense in Sign of the Moon)) Dovewing is the 3d.
Ivypool is spying on the Dark Forrest.
Their father ((Burchfall)or whatever?) goes to the DF.
Blossom fall goes too.
Frost(???) falls in the tunnel that HollyLeaf ran into.
Lionblaze and Jayfeather find a tuff of HollyLeaf's fur.
Longtail gets killed by a falling tree and Briarlight gets after him and gets her back legs crumpled.
Briarlight almost gets killed by a dog.
Cinderheart is Cinderpelt.
Cinderheart likes Lionblaze.
The Dark Forrest is rising.
