Warriors: Graystripe's Adventure

When the Twolegs destroy the warrior Clans' forest home, ThunderClan deputy Graystripe is captured trying to help his comrades escape! Trapped in the pampered life of a kittypet, Graystripe gets all the food and shelter he needs from his affectionate Twoleg family—but the forest is calling him. When he makes friends with a feisty kittypet named Millie, she encourages him to go in search of his lost friends. But will Graystripe ever find his way back to the Clan? Source: Tokyopop
