This was preceded by 'Travellers' (1994), and followed by 'Westsiders: Stories of the Boys in the Hood' (1999), which focused on the ambitions of aspiring hip hop artists in Los Angeles. Another non-fiction title, 'A Superhero for Hire: True Stories from the Small Ads' (2005), suggests a continued exploration of unique human endeavors and stories found in unexpected places.
