The Last Binding
In a secret magical world hidden within Edwardian England, this historical fantasy series follows a forbidden romance between a magic-user and a non-magic user. They investigate a series of mysteries tied to ancient magical pacts, facing danger and societal prejudice as their relationship deepens.
The series should be read in publication order to follow the developing relationship between the main characters and the overarching magical mystery. Start with "A Marvellous Light," followed by "A Restless Truth," and then "A Power Unbound."
There is a related novella, "The Ruin of a Rake," which explores a different couple within the same magical world and can be read after "A Marvellous Light" or as a standalone.
The author has confirmed that a fourth book, "A Mirror Mended," is planned to conclude the main story arc of the series.
