The Donnybrook is a three-day bare-knuckle tournament held on a thousand-acre plot out in the sticks of southern Indiana. Twenty fighters. One wire-fence ring. Fight until only one man is left standing while a rowdy festival of onlookers - drunk and high on whatever's on offer - bet on the outcome.
Jarhead is a desperate man who'd do just about anything to feed his children. He's also the toughest fighter in southeastern Kentucky, and he's convinced that his ticket to a better life is one last fight with a cash prize so big it'll solve all his problems. Meanwhile, there's Chainsaw Angus - an undefeated master fighter who isn't too keen on getting his face punched anymore, so he and his sister, Liz, have started cooking meth. And they get in deep. So deep that Liz wants it all for herself, and she might just be ready to kill her brother for it.
As we travel through the backwoods on the way to the Donnybrook, we meet a cast of nasty, ruined characters driven to all sorts of evil, all in the name of getting their fix - drugs, violence, sex, money, honour. Donnybrook is exactly the fearless, explosive, amphetamine-fuelled journey you'd expect from Frank Bill's first novel . . . and then some.
