What's the story?

When the sea-dwelling Alpha arrived on the shores of Coney Island, they forever changed the course of Lyric Walker's life. She's forced to cut herself off from strangers and finds herself at odds with her family and her best friend. Much of the human race views the Alpha as an invading force, but when politics force Lyric's high school to accept them as students, she reluctantly has to help protect them. Before she quite knows what's happening, she's paired with Fathom, the Alpha crown prince. Lyric and Fathom must learn to trust each other, especially when they learn that an even greater danger is headed their way.

Is it any good?

When denizens of the deep arrive on the shores of New York, it's an opportunity for an unusual and gripping alien invasion tale. Comparisons to current conflicts about immigration are a tad heavy-handed, yet the atmosphere of suspicion and desperation gives the scenario some extra narrative power. Even though Lyric, her family, and her best friend Bex are portrayed as three-dimensional characters, they're still capable of surprising the reader with their hidden strengths and weaknesses.

Lyric's star-crossed romance with Fathom may be somewhat predictable, but their scenes together do add spark to the proceedings. All in all, UNDERTOW is a promising series start, and its climax promises more romantic adventure to come.

  • How can politicians use the media to manipulate public opinion? How are they able to present falsehoods as truth?
