This story of only 2,581 words is a stellar example of what can be achieved when for the first time we take the point of view of a character who we know exists but whose voice has never been heard.  It is said that every person is the hero of his own story, and in The Serpent's Tale the basilisk who was imprisoned by Salazar Slytherin gets her chance finally to speak for herself.  And she does have a tale to tell.  She's a completely sentient being, not a mindless monster.  And her point of view gives us food for thought.  We see her longing to be free and to be with other snakes, to experience the pleasure of nature, and to be out of the control of Salazar.  We see Salazar and his schemes through her eyes, and her disdain for him, even though she cannot escape from the Chamber of Secrets,and her disgust at having to live there, neglected by the self-serving Salazar.

The story is set in the days immediately before Salazar Slytherin leaves the castle and his three fellow Founders, after putting his basilisk into a centuries-long sleep, to await the coming of the heir.  A truly unique, eye-opening story.  Highly recommended.
