Once Upon a Heist — Ashley Hodges Bazer

Emberly is a simple girl, leading a simple life of servitude to her stepmother and stepsisters. But when her friend Gwyn shows up at her doorstep, proposing a scheme that would free her and a ragtag bunch of fairy tale heroines from their unsatisfactory lives, Emberly accepts. Their mission? Steal jewels from the kingdom's six princes. Each heist involves danger and mystery, and soon Emberly discovers a secret that could finally free the kingdom of Paladia from the clutches of evil queen Venefica. Or utterly destroy them all.
