This was an adorable, if fluffy, issue. It was a fun, lighthearted team-up between Batgirl and Supergirl with a silly plot to hold together some cute characterization and some great dialog. I would definitely read more adventures of Stephanie and Kara! They make a good team. I also really like one-shot stories like this that break up the heaviness of the over-arching plots and often make for some of the most fun issues.
