Undertow

Mysterious beings appear on the shores of dystopian Brooklyn in a saga blending action, suspense, and romance, by the author of the Sisters Grimm series. Sixteen-year-old Lyric Walker's life is forever changed when she witnesses the arrival of 30,000 Alpha, a five-nation race of ocean-dwelling warriors, on her beach in Coney Island. The world's initial wonder and awe over the Alpha quickly turns ugly and paranoid and violent, and Lyric's small town transforms into a military zone with humans on one side and Alpha on the other. When Lyric is recruited to help the crown prince, a boy named Fathom, assimilate, she begins to fall for him. But their love is a dangerous one, and there are forces on both sides working to keep them apart. Only, what if the Alpha are not actually the enemy? What if they are in fact humanity's best chance for survival? Because the real enemy is coming. And it's more terrifying than anything the world has ever seen.

In the first book of Michael Buckley's Undertow trilogy, the Alpha arrived and the world was never the same. At the start of the second book, most of south Brooklyn is in ruins and the nation is terrified. Nearly everyone that Lyric Walker loves is either missing or presumed dead, including the mesmerizing prince Fathom. It's up to Lyric to unite the Alpha before the second wave of a cataclysmic invasion wipes out mankind for good. The Undertow trilogy is an unforgettable reading experience that author E. Lockhart calls, "Allegorical and romantic, the book nevertheless reads like an action movie with especially awesome CGI."

After seven months as a captive of Minerva, the insane Alpha queen, Lyric Walker has escaped to the surface. Her only goal is to warn the world about the Great Abyss. When she finally arrives back in Coney Island, she discovers a world she never expected, one where humans and Alpha are finally working hand in hand to rebuild the country. But she soon discovers that an old enemy allied with an old friend may kill them all before the monsters get their turn. Where will Lyric's loyalties, and her heart, lead her? With nail-biting action and romance, Michael Buckley's epic trilogy draws to a stunning conclusion.
