The Tail of Emily Windsnap, by Liz Kessler
My daughter and I just loved this story about a little girl (Emily) that finds out she is half-mermaid. Her mother is phobic about water and doesn’t allow her daughter to ever enter the water even though they live on a houseboat surrounded by water! When she finally does experience being submerged in water Emily finds out that it causes her to turn into a mermaid! At that point, her story gets really interesting as she learns her father (who has been absent from her life) is a real-live mer-man! Adventures ensue as she makes friends with a mermaid her age & seeks out her long-lost father underwater.
I can’t say enough about this book…its so well written from a literature perspective (future “classic”!), as well as the plot keeps you wanting more. Luckily there are 2 more books in this series! At the writing of this, we’ve read the 2nd book but not the 3rd…the 2nd was equally good and I expect the 3rd to be as well.
