Promised in Fire (Of Dragons and Fae, #1)

Mermaids, like many other creatures of mythology and folklore, are regularly depicted in literature, film, music, and popular culture. In the folklore of some modern cultures, the concept of the siren has been assimilated to that of the mermaid. For example, the French word for mermaid is sirène, Italian sirena, and similarly in certain other European languages. This usage existed by the Middle Ages.
