Mercedes Lackey says:
To write or enjoy fantasy requires an open mind and heart, and the ability to believe that things are not always what they seem.
There are fantasy romances, fantasy mysteries, heroic fantasy, modern-urban fantasy, historical fantasy, dark or horror fantasy, alternative-history fantasy, political fantasy and even Western fantasy.
Fantasy is one of the last bastions of 'moral fiction.'
Good triumphs over evil, the wrongdoers get their just deserts, and all ends well.
(Can you tell that fantasy books are one of my favorites to read? And she is one of my favorite authors.)
