I really, really enjoyed this addition to the Buffy series - it's one of the best of the young adult length novels. Buffy dusts two teen vamps, angering their mother, who raises a goddess of revenge to punish her. Now Buffy must undergo a test by Nemesis (the goddess). If she fails, her mother dies. I really enjoyed the whole test sequence, especially the part where Buffy has to see what would have happened if she had failed to save her friends at various points. Very emotional. Anyway, I can't say enough good things about this book, so if you are a Buffy fan, just go and read it!
