The choices they make now could affect ThunderClan for generations to come... and with an unexpected enemy preparing to attack, their courage and strength will be needed more than ever if the Clan is to survive.
Erin Hunter is the pen name used by the several authors of the Warriors novel series and the Seekers novel series.
"Erin Hunter is inspired by a love of cats and a fascination with the ferocity of the natural world. As well as having a great respect for nature in all its forms, Erin enjoys creating rich mythical explanations for animal behavior, shaped by her interest in astrology and standing stones."
