Warriors : Thunder - A Starless Clan Book 4
(Juvenile Book)

Frostpaw was told to trust no cat, but a brutal attack has left her gravely injured, and she'll need to depend on someone. When help arrives in the unexpected form of Nightheart, she convinces him to protect her as she follows StarClan's cryptic directions toward the roots of RiverClan, where Riverstar has promised she'll find the answers she's been so desperately seeking. Nightheart, desperate to step out of the shadow of his family legacy, is eager to take the chance to be the hero of his own story--even if it means putting the future of the Clans over everything, including the cat who left her whole life behind to follow him back to ThunderClan. As Sunbeam prepares to tackle the trials that will let her join a new Clan, she's surprised to be facing them alone. But her chosen home is facing changes much larger than one potential new warrior, and as tensions run still higher between Tigerstar and the other Clan leaders, her fate is far from the only thing that hangs in the balance.
