"What's next for our favorite mergirl? . . . A fun fantasy with
well-drawn characters and engaging suspense." -- Booklist
A field trip to a mysterious island quickly turns into an adventure when
Emily and Aaron discover a ghostly ship that no one else can see.
Searching for answers only leads to more questions -- until Emily and
her friends uncover the story of a ship caught between land and sea, day
and night . . . life and death. Only Emily, with her ability to
transform from mermaid to human, can enter Atlantis to try to bring the
ship's passengers back before the portal is closed forever. Will she be
able to resist the allure of Atlantis and return home before it's too
late?
