Under Her Spell — J.A. Ferguson

Madeleine Nightingale is her brother's magician's assistant. They travel town-to-town performing as The Magic Nightingales, but her brother dreams of being on the stage in a fine London theater. Madeleine wants him to be happy, so when she hears a famous theater owner will attend a Faire at Sheffield Priory, she knows it's their chance. She will make sure their show goes perfectly...even if she has to use a bit of the true magic that has been her secret gift since childhood.

Christopher Sheffield has arranged a Faire to celebrate Queen Victoria's Diamond Jubilee. But he has an ulterior motive. He wants his mother to receive his mistress Allegra so he can connect his life in London with his life in the country. Everything is going according to plan until he chances upon Madeleine Nightingale and her brother. Thoughts of Allegra fade when he draws Madeleine into his arms. But Madeleine isn't the easy conquest he'd hoped. He'd like to forget her, but there is something unquestionably magical about the magician's assistant.
