In this thrilling postapocalyptic tale set in 2099, after civilization was forced underwater by global flooding, a young Muslim woman searches for her unjustly imprisoned father amid the remnants of Great Britain. British-Afghan Leyla McQueen, 16, a champion submersible racer, hopes to free her father (jailed for "aiding and abetting citizen suicides" among sufferers of an underwater malaise called "the seasickness") by winning the prestigious London Submersible Marathon. When that hope doesn't pay off, she sets out into the treacherous ocean to find him herself, accompanied by Ari, a mysterious young man sent by her grandfather to protect her. Despite Leyla's insistence that she doesn't need any help, the waters are filled with enemies, including the genetically engineered Anthropoids who prey upon humans, and the authorities who want to prevent Leyla and Ari from discovering the truths hidden in the dark depths of a drowned world. Shah's strong debut, first in a planned duology, is vividly described and emotionally rich. Despite predictable plot points and an insufficiently explained underwater setting, the strong premise and underlying sense of excitement make this a fast-paced, wholly enjoyable adventure. Ages 12--up. Agent: Rebecca Podos, Rees Literary Agency. (Oct.)

Sixty-five years ago, Leyla's world was above the waterline. But in 2099, the earth has drowned and the people with it. Leyla lives alone with her father, an astronomer, and she makes ends meet by competing in sub races around famous London landmarks. Or she did until her papa was arrested for terrible crimes she's certain he didn't commit. Running out of time, running out of money, and coming up empty on answers, Leyla determines to find and rescue him herself. When she discovers a whole underwater world, her life gets much more interesting and dangerous than she ever imagined it could be. While the book seems to end on a firm note, there could easily be more stories in this undersea dystopian world. Shah's prose sometimes turns melodramatic ( Hope had abandoned them to the wrath of all the waters ), but this is a fine postapocalyptic novel that hits a timely note with its climate-change narrative. A solid purchase for large collections.--Stacey Comfort Copyright 2010 Booklist

Gr 7 Up--The year: 2099. The place: London. Only, this is a London completely unfamiliar to readers. After a devastating disaster 65 years ago, the entire world has been left under a thousand feet of water. All of surviving humanity has adjusted as well as possible, living inside air-tight homes, driving submarine vehicles, and hoping for the day they can return to the surface world. Enter 16-year-old Leyla McQueen, a British Muslim of Afghan descent desperately fighting to have her scientist father freed from a government prison. So when she wins a coveted spot in the London Submersible Marathon, the grand prize of which is the champion's greatest desire, Leyla knows this is her best shot. But when the events of the race lead to an adventure greater than Leyla could ever have imagined, will she be prepared to do whatever it takes to see her father again? Shah's debut is a fast-paced masterpiece from start to finish. Readers will fall in love with passionate, persistent Leyla as well as her secretive, swoon-worthy companion Ari. While the tropes of dystopian fiction--corrupt government, fear of the unknown--will be easily recognizable by fans of the genre, Shah has skillfully shaped a gorgeous world unlike any those fans have seen before. But be forewarned: the book ends on a jaw-dropping cliff-hanger, so a sequel is presumably forthcoming. VERDICT An #OwnVoices title for fans of Rhoda Belleza, Amie Kaufman, and Roshani Chokshi. Highly recommended.--Kaitlin Frick, New York Public Library
