Speaking From Among the Bones

In the fifth book of the New York Times bestselling series, featuring Flavia de Luce, Alan Bradley pens his most chilling mystery yet, and introduces a new character into the mix whose actions will have lasting consequences on Bishop's Lacey, the de Luce family, and especially Flavia herself.
     When the tomb of St. Tancred is opened at the village church in Bishop's Lacey, its shocking contents lead to another case for Flavia de Luce. Greed, pride, and murder result in old secrets coming to light--along with a forgotten flower that hasn't been seen for half a thousand years.
