Is there a chance Twigpaw and Violetpaw are Pebbleshine's kits? 

If you don't know, Pebbleshine was taken by a Twoleg trying to catch chickens in Hawkwing's Journey. She was expecting Hawkwing's kits. He never found her. But in The Apprentice's Quest, Twigpaw and Violetpaw, then kits, were found motherless. Is there a chance Pebbleshine was their mother, and abandoned them to try to find SkyClan

Also, will SkyClan come back in Shattered SkyWe all know Darktail drove out SkyClan out of the gorge, then followed Alderheart, then an apprentice on a quest, back to Clan territory. He took over ShadowClan when the Clan exiled Rowanstar. Bringing back SkyClan to get revenge on Darktail may be the only possibilty to rid of Darktail and the rogues once and for all.
