Thunder and Shadow is the second book in the A Vision of Shadows arc.
It's been nearly a moon since Alderpaw returned from his quest, unsuccessful but not empty-pawed. The two kits he found, Twigkit and Violetkit, have been taken in by two Clans: ThunderClan and ShadowClan. There is little hope for a reunion, as tension between the Clans begins to rise in the face of a new threat. The same vicious group of rogues that drove out SkyClan has traced Alderpaw's path back to the territories around the lake—and ShadowClan may be the next to fall.
- The original working title was confirmed on Kate's blog to be The Lost Clan. This has now been changed to Thunder and Shadow.
- What had happened to Spiderleg will be revealed in this book.
