Gawain

Sir Gawain is a knight as good as his word. Fiercely loyal to Arthur, he will do anything to serve his king. So when a hideous crone promises to give Arthur the answer to a riddle that will save his life, if only Gawain pledges to marry her, the knight does not hesitate.
 
But the loathly lady is not who she appears to be. In truth she is the lovely Aislyn, former apprentice to a sorceress, and once desperately in love with Gawain, who rejected her because of her magic—or so she believes. Now she has transformed herself so she may exact her revenge.
 
Yet Gawain's gallantry and courteous treatment soften Aislyn's bitter heart, and she is horrified to discover she has actually been enchanted.  Only a kiss given with love can break the spell and restore her to the beautiful maiden she truly is.
