Bonnie is a girl from District 8. She looks to be younger than Katniss in Catching Fire which leads her to believe she is not her age. She has a strawberry birthmark over one of her chocolate brown eyes and has very pale skin.
Once the uprising in District 8 begins in Catching Fire, the district appears to be under rebel control, until the Capitol deploys Peacekeepers "by the thousands" to take back the district. The rebels are beaten down and defeated. As punishment, as well as to regain order in the district, the Capitol places a full lockdown state on District 8 for approximately one week, with no food or coal. Finally, when they are allowed to go back to work, Bonnie and Twill are late getting from the school to the factory. The factory is bombed before they made it there, which saves their lives, but regretfully kills Twill's husband and Bonnie's entire family. The two disguise themselves in the Peacekeeper's uniforms and escape to the woods surrounding District 12. However, Bonnie has twisted her ankle, and because of that, she has to use a branch as a crutch, which slows her down considerably. Also, Bonnie's peacekeeper outfit is too big for her because it was made for Twill's husband, who died in the factory explosion, so Bonnie has to wear it on the journey to District 13.
Soon, she and Twill arrived at District 12, where they met Katniss Everdeen. They informed Katniss that they intend to go to District 13, because they believe there were others there who support the rebellion.
She reminds Katniss of Rue when they were in the cement shack. Katniss offers her a cheese bun (Katniss' favorite), and Bonnie replies, "Is this all for me?," which reminds Katniss of Rue in the arena, when they were eating groosling drumsticks.
In Mockingjay, Bonnie and Twill did not make it to District 13, so their fates are unknown, but Katniss states that they are most likely dead.
- Bonnie and Twill do not appear in The Hunger Games: Catching Fire.
- Bonnie and Twill were removed from the film adaptation for Catching Fire as the filmmakers did not want to spoil the ending of the movie and the plot of Mockingjay for audiences who hadn't read the books.
