Not Unfortunate

Isilia Greygrove looks exactly like her twin sister Isolda… but in fact, she is a changeling that the fairies of the Good Court left in the cradle of a human infant. Sili has always known that she is different from others. Her own unpredictable magic forced her to flee with Isolda from their hometown, erasing all memories of herself. And due to a botched robbery, the sisters were forced to search for a treasure whose mystery goes deep into the history of humans and fairies.
