End Game Characters
by Adriana Locke

End Game has a small-town, lake-cabin feel with a wide supporting cast around two central characters: Branch Best, the football player nicknamed Lucky, and Layla James Miller, Finn's younger sister and a freelance writer. Their families, friends, exes, and neighbors keep the story moving.
On this page you'll find each character's role, from Finn's protective brother routine and Poppy's humor to Callum's messy ex behavior and the cabin neighbors who show up at the right time. Descriptions cover arcs and relationships, plus smaller players like bartenders, doctors, and teammates, without giving the ending away.
Main Characters
