The Return (#1)

Just one moon after Squirrelpaw and her brothers are apprenticed, tragedy strikes, and one of FernClan's warriors is found dead in the forest. Wrongly accused for killing her mother, the young she-cat is banished to the life of a rogue.
The coming of a harsh Leaf-Bare means trouble for all the cats living around the river, and Squirrelpaw is forced to trudge back into the life of a clan cat and rely on her clanmates once more.
Though her loneliness has vanished and her stomach is full, their aggressive neighbors are full of greed for land. Lilypaw has been acting odd, always nodding off in practice and eating everything she can stuff down. Whispers of shadows lurking in the woods beyond have begun to haunt the camps, scaring cats into fits of silent screams as they sleep.
Danger has come to their home, and Squirrelpaw is left hanging from a thread.
