Yes, there will be a Super Edition entitled, "Bramblestar's Storm."
Bramblestar is the current leader of ThunderClan. He was made Bramblestar in "The Last Hope", after the death of Firestar, the previous leader.
Eventually, yes.
Goldenflower
Bramblestar died after being possessed by an imposter posing as the spirit of Ashfur. The imposter caused chaos within ThunderClan by manipulating Bramblestar and ultimately leading to his death.
Bramblestar loses his lives in "Warriors" series by being injured or killed in various battles, conflicts, or accidents. Each time Bramblestar dies, he loses one of his nine lives, which is a concept in the series where leaders of the Clans have multiple lives to serve their Clans.
Probably yes
Bramblestar
Im pretty sure that it will show thunderclan since the title is Bramblestar "star" so it must mean after he recieves his nine lives.
No, Squirrelflight is infertile. She cant have kits due to a past injury; during Eclipse (book 4 in Power of Three) when Thunderclan fought Windclan, she suffered a massive gash to the stomach which, in turn, made it impossible for her to have kits.
I think you mean Sparkpaw. She is Alderpaw's sister and is a daughter of Squirrelflight and Bramblestar. Her first appearance is in The Apprentice's Quest, the first book of A Vision of Shadows. Again, there is no sparklepaw, very sorry if this doesn't help.
Hollypaw becomes a mother in the book "Bramblestar's Storm" when she has three kits with Fallen Leaves named Sorrelkit, Mintkit, and Larkkit.
Squirrelflight is not infertile. She and Bramblestar have kits together in the Warrior Cats series.
