enchanting alternative history gaslight fantasy with steampunk. Kept me up past my bedtime more than once on a work night. 
 This story is one of a mirror Europe where history went totally differently and Elliott has created a very rich alternative history for most of the world. We visit both England and the Caribbean, which isn't under European control. It is a story of two sisters' unconditional love for each other (they are bea really). There is a love story as well but it is always second to the sister story. The characters are as rich and diverse as the backgrounds and the magical world is really interesting.
