Book excerpt: A cross-Atlantic collaboration, Hobo Mom was drawn simultaneously. Both cartoonists’ clean line styles fit together perfectly to tell the story of Tom, who lives a simple life with his pre-teen daughter, Sissy. Her mother, Natasha, who left to hop trains and has become a vagrant, shows up on the doorstep of the family she abandoned years ago. There, Natasha finds an upset husband (who is still deeply in love with her), and a little girl yearning for a mother. Can someone who covets independence settle down?
