Emily Windsnap and the Land of the Midnight Sun By: Liz Kessler

Dangerous storms are brewing in the ocean, caused by the nightmares of Neptune, King of the Sea. Convinced that his dreams herald an approaching threat. Neptune sends half-mermaids Emily Windsnap and Aaron on a top-secret mission to the land of the midnight sun, an icy world of mountains and glaciers. As they search for the source of the trouble, Emily and Aaron uncover a mystery more dangerous than they ever imagined — along with Neptune’s darkest secret.
