"Beware, Lief of Del! You might have faced the Kobb of the Isle of the Dead and survived, but I see creeping darkness in your future. The way upon which you have set your feet leads to disaster. Heed my warning, and turn aside from it!"
— Ava warning Lief
Ava grew up alongside her brothers Tom and Jack in the Plains territory. The three of them shared a mental connection that allowed them to know what the others were doing, even from miles away. On her own, Ava showed the ability to tell fortunes. When they came of age, Ava set off for The Finger, a peninsula on Deltora's western coast, to set up a shop. Her symbol is the eye.
Isle of the Dead
Knowing that Lief, Barda, and Jasmine had a run in with his brother, and guessing their next movements accordingly, Tom sent them a letter informing them of Ava, along with a bag of Pepperment Fancies. Before the companions reached her, however, Laughing Jack abducted Ava and took her place. He tried to send the companions to their deaths on Blood Lily Island, but they survived to destroy the Sister of the West. When Jack kidnapped Jasmine, he revealed Ava and told Lief to place the Belt of Deltora on her, so that he may dispose of them both. Lief refused, and Ava warned her brother of dead hands coming for him in his future. This came to pass, as Jasmine caused Jack to break the vow he swore to his undead crew, binding Jack to the oars of his ship, The Lady Luck.
The Sister of the South
Ava warned Lief of a 'creeping darkness' she saw in his future, and warned him to abandon his quest. This prophecy also came true in the form of the two headed monster summoned by Paff. She later took a holiday to attend Lief and Jasmine's wedding.
Ava is thin with tangled brown hair. She powdered her face chalky white. Her eyes are gleaming white. Ava wore a hooded cloak made entirely out of white and black feathers of sea birds, which her brother, Jack, stole and used as a disguise when posing as her to trick Lief, Barda and Jasmine.
Ava, like her brother, is a person of business. Her sign can be read from any direction, much like Tom's, and she also gives a free gift to those who ask. Ava also uses her powers to warn others of what she sees in their near future.
Ava shares a mental link with her siblings that allows her to know what they are doing, from miles away. On her own, she showed the ability to predict to tell fortunes. It can be argued that Ava might have had a way with business, being a shopkeeper.
