Erin Hunter

Harboring growing suspicions about the trustworthiness of SkyClan newcomer Sol, a wary Leafstar is challenged to protect her clanmates when Sol's actions threaten everyone with disaster.

"Ravenpaw has settled into life on the farm, away from the forest and Tigerstar's evil eye. He knows that leaving the warrior Clans was the right choice, and he appreciates his quiet days and peaceful nights with his best friend, Barley. But when five rogue cats from Twolegplace come to the barn seeking shelter, Ravenpaw's new life is threatened. He and Barley must try to find a way to overpower the rogues - before they lose their home for good."...

"Leafstar is struggling to keep SkyClan united in the wake of the flood that destroyed their camp, but her Clanmates are scared of what might happen next. Meanwhile, Sol continues to demand that Leafstar make him a warrior, but Leafstar isn't sure that Sol will ever be read to embrace the warrior code. As SkyClan faces another devastating challenge, Leafstar must figure out what is best for her Clan - once and for all." - from back cover.

Leafstar, having escaped from the Twoleg's home with the help of Billystorm and her Clanmates, finds more trouble when Sol joins the ranks of the SkyClan and his actions bring about a disaster, leaving Leafstar to decide if trusting a stranger in her ranks is worth risking the clan's future.
