When supervillain Lex Loser threatens the world with a computerized neutron bomb, Heroes United for Humanity turns to its least likely hero to save the day. Supergeek Clark Kendall is humanity's last hope for survival, but he can't do the job alone. He needs the help of long-lost superheroine Blossom Breeze. Blossom doesn't have a clue about her heritage. She's smart, cute, and sassy-and so not into geeks. Clark's got three short days to trigger the unique cascade of hormones that will switch on Blossom's superheroine gene. Unfortunately for humanity, Clark's superpowers don't extend into the bedroom. Or do they?
