THE SCANDALOUS SISTERHOOD OF PRICKWILLOW PLACE by Julie Berry
I loved this splendidly wicked book. I listened to the audiobook narration of this twist on the Victorian boarding school mystery novel, and it was glorious. I didn't know what to expect and when in the first few pages, the headmistress and her brother drop dead from poison, and the girls subsequently decide to bury them instead of report it, I thought, "how macabre!" The girls, who have wonderful monikers like "Smooth Kitty," "Disgraceful Mary Jane," and "Stout Alice," decide to try and convince everyone that their headmistress is still alive so they can avoid being sent home.
