"Cape And Cowl" by Ann Douglas (annd@pop.tiac.net). Here we're back to Supergirl as I know and love her. At the beginning of the story, a small jet is in extreme danger. The Girl of Steel, who happens to be in the area delivering a heart for a transplant operation, rescues the pilot and passenger by bringing the jet in for a gentle landing. By sheer chance, the passenger on the jet happens to be Barbara Gordon, junior congressional representative from Gotham City, whose secret identity is Batgirl. The loss of the engines on the jet was no accident; it was sabotage by evil agents of Quraq. Supergirl and Batgirl quickly combine to subdue Crimson Rose, the main Quaraqi agent; and then they disclose their mutual attraction to each other. Then a good time is had by all.
This is a very nice story. I guess you could say it's not great literature - just a kids' comic book story that happens to be banned for children. But this author does a great job of setting up a plot with details that are both interesting and consistent. In addition, the sex between the two superheroes seemed perfectly plausible to me. The aspect that I like best about Ann Douglas's stories is that her characters have genuinely interesting personalities.
