Seventeen year old Avery Anderson is convinced her senior year is ruined when she's uprooted from her life in DC and forced into the hostile home of her terminally ill grandmother, Mama Letty. The tension between Avery’s mum and Mama Letty makes for a frosty arrival and unearths past drama they refuse to talk about. Every time Avery tries to look deeper, she’s turned away, leaving her desperate to learn the secrets that split her family in two.

While tempers flare in her avoidant family, Avery finds friendship in unexpected places: in Simone Cole, her captivating next-door neighbour, and Jade Oliver, daughter of the town’s most prominent family - whose mother’s murder remains unsolved.

As the three girls grow closer - Avery and Simone’s friendship blossoming into romance - the sharp-edged opinions of their small southern town begin to hint at something insidious underneath. The racist history of Bardell, Georgia is rooted in Avery’s family in ways she can’t even imagine. With Mama Letty's health dwindling every day, Avery must decide if digging for the truth is worth toppling the delicate relationships she's built in Bardell - or if some things are better left buried.
