Leonette Tarly (formerly Leonette Tyrell) is the mother of Garth II Tarly and Bonifer Tarly, and the widow of Quentin Tarly. She is described as a shrewd and capable woman who ruled Horn Hill throughout her son's six year absence, and continues to rule Horn Hill until her son takes the mantle.
She is one of the last surviving members of House Tyrell after the Ascent of the Lion, besides her nephew Olyvar Tyrell and niece Meredyth Tyrell.
History
Leonette was the firstborn child to Lord Paramount Luthor Tyrell and Lady Rohanne Florent in 452 AC. She had two younger brothers, Baelor Tyrell and Lyonel Tyrell, both of which are now deceased. As a child, she was betrothed to the then Heir of Horn Hill, Quentin Tarly, as a plan by her grandfather, Lord Paramount Theodore Tyrell, to reunite the Reach after the Westerosi civil war known as the War of the Split Stag.
Important Events
Second Era
Leonette learns of the death of her husband Quentin, and her firstborn son, Garth, following the Ascent of the Lion. With her only remaining son, Bonifer, still missing and presumed dead, Leonette assumes the duties of the Lord of Horn Hill.
Fourth Era
Bonifer returns to Horn Hill after his adventures around Westeros and Essos with Beren Merryweather, Varus, Tyro and Hycae in tow. Bonifer assumes the lordship from his mother, who remained critical of his inability to lead.
Eighth Era
After a fight with Bonifer on his unwillingness to focus on his lordly duties, Bonifer leaves Horn Hill suddenly and Leonette is forced to reassume the lordship in his absence. Despite being critical of his ability to lead House Tarly, Leonette worries for his safety.
Horn Hill is continuing to suffer the effects of famine caused by the blight in the Reach as well as the onset of winter. The stores within Horn Hill are suffering badly and plans are made to seek assistance from the marcher lords in the Stormlands for assistance. A letter from Starfall arrives, offering a trade deal of food between Dorne the the Reach, which Leonette suspects is a ploy by the Dornish to take advabtage of their misfortune and monopolise the Reach's food supply for their personal profit.
Pressure increases on Leonette to find a solution to their famine as whisperings of a smallfolk uprising begin to circulate around the castle.
Matters are further complicated by the murder of the assisting Maester Erryk, who was poisoned in the rookery. The murderer also released all of the ravens from the rookery, essentially disabling Leonette's ability to communicate with the outside world as a blizzard descends on Horn Hill. Leonette then addresses the people of Horn Hill in an effort to rally their support and keep the peace, unknowing that a conspiracy is already quietly underway.
