Dark River — Erin Hunter

THERE WILL BE THREE. KIN OF YOUR KIN...WHO HOLD THE POWER OF THE STARS IN THEIR PAWS

Lionpaw, Hpollypaw, and Jaypaw -- grandchildren of the Clan leader Firestar -- are thriving as the newest ThunderClan apprentices. Yet with their new responsibilities come new experiences, new power and secret dangers.

Lionpaw makes a friend -- and a discovery -- that must be kept hidden: Jaypaw learns a secret that could benefit ThunderClan only by bringing harm to others; and Hollypaw knows something that could avert a battle, if only she could convince the rest of her Clan. Prophecy looms, ominous forces threaten to tear them apart, and each young cat discovers darkness: in the past, in the Clans and in themselves.
