'School Captain Astrid Pollard is on fire. Ever since she was assigned that oral presentation on Joan of Arc life has sort of, well, spontaneously combusted. People are looking at her funny. The frogs in Biology are singing to her.
'Help comes in the form of school pariah Hadley who convinces Astrid that this might be some kind of divine calling or a mission — just like Joan’s. But something darker is swirling beneath the mysterious vigil, beneath the oral presentation, beneath the playground … and it explains the radical cracks in Astrid’s strangely magical universe.'
