She is a lonely widow and mother to two boys who attend a boarding school far away. When Serafina takes lodging at Luzie’s house, Luzie’s compositions hold a power she never imagined. Margerit recognizes the power but is skeptical of what role music might play in theological mysteries. Luzie can’t see the power she has so she is skeptical of them both, but finds herself swept up in Margerit’s circle. Jeanne having launched an aspiring violinist in the previous book is poised to launch Luzie as the first female composer of Operas in Rotenek.
