In a post-Brexit world, the Myths and Legends of the British Isles are alive, and ready for war

As Great Britain struggles to face its new reality in a post-Brexit world, the government's affable-seeming Prime Minister Colin Dubois plays a man of the people, while simultaneously purging the country of what he thinks of as "undesirables".

Ajia Ryker is a young mixed-race woman who in her spare time, when she is not working as a bike courier, runs around London daubing Banksy-esque subversive graffiti on walls. When she runs afoul of the authorities, Ajia finds herself in the world of eidolon, mythical beings who are living incarnations of an idea, from Oberon, King of the Faeries to Robin Hood.

As Dubois seeks to crown himself as the new King Arthur with his own round table of knights, using ancient powers to achieve his agenda, only Ajia and her new allies can stop him.
