'Arlen’s twin sister was stolen by the fey moments after her birth. When he is sent to advise the king, his plan to search for his missing sister must be put on hold — until he realises that she might be the key to bringing peace to the kingdom.

'Agata doesn’t know she’s part mortal. Raised by the queen of the fey, she despises mortals just as much as Titania does. When Agata accidentally encounters the twin she was separated from at birth, she discovers that everything she thought she knew about herself is a lie.' (Publication summary)
