Scales and Legends — B. Kristin McMichael

All three books in the Merworld Trilogy are now available in one collection. Books 10-12 in the night human world are a standalone series that follows teenager Whitney in her move to Florida to leave the night human world. Whitney was looking for a fresh start, and that was what she thought she had got, until she finds out about the not-so-human people that call her small town home when they aren't in the water. Leaving the night human world behind would be easier if her swim instructor wasn't keeping a secret. Follow Whitney on her journey from an ordinary girl to a legend.
