A boy and his cat. It's an unconventional friendship, perhaps, but for Charlie and Lily, it works beautifully. Charlie chose Lily from among all the cats in the shelter. He didn't frown, the way other humans did, when he saw her injured back leg - the legacy of a cruel previous owner. Instead, Charlie insisted on rescuing her. Now Lily wants to do the same for Charlie. She's the only one who's seen the bruises on Charlie's body. If she knew who was hurting him, she'd scratch their eyes out. Lily knows what it's like to feel helpless. But she also knows that you don't always have to be the biggest or the strongest to fight fiercely for the ones you love . . .
