On the Edge of the Dark Sea of Darkness (The Wingfeather Saga) by Andrew Peterson

Once, in a cottage above the cliffs on the Dark Sea of Darkness, there lived three children and their trusty dog, Nugget.

Janner Igiby, his brother, Tink, and their disabled sister, Leeli, are gifted children as all children are, loved well by a noble mother and ex-pirate grandfather. But they will need all their gifts and all that they love to survive the evil pursuit of the venomous Fangs of Dang, who have crossed the dark sea to rule the land with malice. The Igibys hold the secret to the lost legend and jewels of good King Wingfeather of the Shining Isle of Anniera.

Full of characters rich in heart, smarts, and courage, On the Edge of the Dark Sea of Darkness is a tale children of all ages will cherish, families can read aloud, and readers' groups are sure to enjoy discussing for its many layers of meaning.
