Deadly Little Scandals by Jennifer Lynn Barnes

“Think of the White Gloves like the Junior League-by way of Skull and Bones?”

Reluctant debutante Sawyer Taft joined Southern high society for one reason and one reason alone: to identify and locate her biological father. But the answers Sawyer found during her debutante year only left her with more questions and one potentially life-ruining secret. When her cousin Lily ropes her into pledging a mysterious, elite, and all-female secret society called the White Gloves, Sawyer soon discovers that someone in the group’s ranks may have the answers she’s looking for. Things are looking up… until Sawyer and the White Gloves make a disturbing discover near the family’s summer home–and uncover a twisted secret, decades in the making.

No one is quite who they seem to be.
