Query: a good concept badly written

The idea is so good, if only the author could have made it interesting. It is about a world inhabited by people with superpowers. The heroine has to take some tests in order to become a full blown superheroine, while trying not to fall in love with a mere mortal. It reminded me of the old Supergirl comics, except that the heroine was a very silly woman, the hero was uninspiring, and the only interesting person was the villainous cousin. The ending was a cop-out.... Now if this concept had been expanded upon by Nora Roberts or Jayne Ann Krentz, they'd have done a much better job.
