Warriors (Erin Hunter). Omen of the stars

A prophecy foretells that three ThunderClan cats will hold the power of the stars in their paws, but although Jayfeather and Lionblaze know that they are two of the cats in the prophecy, they must determine who the third cat is.

The deadly battle between ThunderClan and ShadowClan is finally over. Now the three cats who are prophesied to hold the power of the stars in their paws are more determined than ever to stop the flow of evil into ThunderClan. As Jayfeather, Lionblaze, and Dovepaw continue to seek answers to the mysterious prophecy that binds them, they learn that another cat may play an essential role in defeating the Dark Forces.

When an outsider appears in the ThunderClan's midst, it drives the Clans further apart and as tension mounts they must decide who they can trust before it is too late.
