The New York Times best-selling series
"An easy sell to girls looking for a friendship story with more than a
touch of make-believe." -- Kirkus Reviews
When Emily Windsnap discovers an old diamond ring during a class hunt
for trinkets, how is she supposed to know that the ring is half the key
to unlocking an ancient curse by Neptune himself? Now, with the ring
stuck firmly on her hand, Emily finds herself under a new curse: in just
a few days, she'll cease to be half-human and half-mermaid and must say
good-bye to one parent forever. Can she possibly find the other missing
ring that will break all the curses? Is there anyone who can help her --
before it's too late?
