Warriors (novel series) Warriors: A Vision of Shadows is the sixth sub-series. The series was originally titled, Warriors: StarClan's Promise. The first book, The Apprentice's Quest, which takes place approximately eight months after Bramblestar's Storm, was released on March 15, 2016. The books' main characters are Sparkpaw and Alderpaw who are Bramblestar's and Squirrelflight's children. The first book, The Apprentice's Quest, starts with each Clan's medicine cats receiving a prophecy from StarClan together, telling them to "Embrace what you find in the shadows, for only they can clear the sky".[42] This is the titular prophecy of the series (A Vision of Shadows). When receiving this prophecy, Jayfeather sees Alderkit (Alderpaw's former name) in his dream, as well as the other medicine cats. Later, he, Leafpool, and Bramblestar decide that Alderpaw should become a medicine cat apprentice. Further into the book, Alderpaw has a vision of the far-off SkyClan. After deciding that Alderpaw's vision relates to the prophecy, Bramblestar sends Alderpaw on a quest to help SkyClan along with his ex-mentor, Molewhisker, Sandstorm, his sister Sparkpaw, and her mentor Cherryfall. While on the quest, they're joined by ShadowClan apprentice Needlepaw. Sandstorm dies along the way. When they reach the gorge where SkyClan lives, they find that they have been run out of their territory by a group of rogues. They decide that they arrived too late to help SkyClan and return back to the lake. On the way back Alderpaw and Needlepaw find two female kits (Twigkit and Violetkit) who lost their mother. Needlepaw suggests that the kits could be "what you find in the shadows". They then take the kits back to the lake and at a full moon Gathering, the clan leaders decide that ShadowClan should take one kit and ThunderClan should take the other. ThunderClan takes Twigkit and ShadowClan takes Violetkit. The second book, Thunder and Shadow, was released on September 6, 2016. It follows Twigkit and Violetkit's lives in ThunderClan and ShadowClan. The two kits struggle to find their place in their respective clans, and feel lonely. However, Alderpaw and Needlepaw befriend the kits, and even arrange for them to meet in secret between the two clans' borders. The Clan cats discover that the rogues from A Vision of Shadows followed the quest cats to the lake, and have made camp near ShadowClan. Meanwhile, the ShadowClan apprentices start to lose faith in the warrior code, and many of them eventually join the rogues, including Needlepaw, who brings Violetkit with her. The third book, Shattered Sky, was released on April 11, 2017. It details the war that ensues between the Clans and Darktail's so called Kin after his annexation of Shadowclan. It heavily focuses on the sisters Twigpaw and Violetpaw as they find themselves on two different sides of a very brutal conflict that will determine the fate of the clans. Battles will be fought, loyalties will be tested, prophecies will be interpreted and as always, cats will die before the clans know peace again.[43] The fourth book, Darkest Night, was released on November 7, 2017.[44] The fifth book, River of Fire, was released on April 10, 2018.[45] The sixth book, The Raging Storm, is set to be released on November 6, 2018.
