Lyric Walker lives near the beach at Coney Island, and she loves her town. One night something or someone came from out of the ocean and onto the beach. She soon finds out that it was not just one but an army of 30,000 Alpha, a five-nation race of ocean-dwelling warriors. The human race is very nervous about what might happen, so they transform the beach into a military zone and forbid contact between the Alpha and the humans. However, the Alpha demanded that their teens be educated, so Lyric and her friends now must go to school with the Alpha teens. Lyric is recruited to meet with the Prince every day, and she hates it because he is rude and uncouth. But...there is something about him that she cannot get out of her mind. Lyric also has her own secret that she is keeping from all of her friends and the prince. If her secret is revealed, her family could be in grave danger. Read Lyric's story in Undertow by Michael Buckley.
I enjoyed this book, but it definitely was set up as a trilogy. In other words, at the end of this one...you are left waiting for the next one which is good for me that it was already out so that I could read it as well--Raging Sea.
