Leevy was Katniss Everdeen's neighbor from District 12. She lived in the Seam and has a younger brother. Leevy was also one of the few survivors who actually made it to District 13 after the bombing of District 12.
A year before Catching Fire took place, Leevy's little brother caught the measles, and Mrs. Everdeen kept him alive. Later, when Gale Hawthorne was whipped by Romulus Thread, Leevy took Katniss Everdeen's arm and asked her if she needed help. Katniss asked her to fetch his mother, Hazelle Hawthorne, and requested for Gale's siblings not to see him in his injured state. Because of this, Leevy offered to watch them while Hazelle went to the Everdeens' home in the Victors' Village to see Gale.
Leevy was one of the District 12 citizens who made it to District 13 after her home district was bombed following the end of the 75th Hunger Games. She was present when Haymitch Abernathy asked a group of people to tell him times when Katniss had moved them emotionally, and mentioned how Katniss had volunteered to take Prim's place during the Reaping for the 74th Hunger Games.
Leevy is described as a girl around Katniss' age with long black hair and gray eyes, typical of people of the Seam.
