From debut author London Shah, comes a thrilling futuristic Sci-Fi mystery perfect for fans of Illuminae and These Broken Stars. In the last days of the twenty-first century, sea creatures swim through the ruins of London. Trapped in the abyss, humankind wavers between hope and fear of what lurks in the depths around them, and hope that they might one day find a way back to the surface. When sixteen-year-old submersible racer Leyla McQueen is chosen to participate in the city's prestigious annual marathon, she sees an opportunity to save her father, who has been arrested on false charges. The Prime Minister promises the champion whatever their heart desires. But the race takes an unexpected turn, forcing Leyla to make an impossible choice. Now she must brave unfathomable waters and defy a corrupt government determined to keep its secrets, all the while dealing with a guarded, hotheaded companion she never asked for in the first place. If Leyla fails to discover the truths at the heart of her world, or falls prey to her own fears, she risks capture-or worse. And her father will be lost to her forever.

Leyla has reunited with her father and rescued him from Broadmoor, the illegal government prison that held him captive--but not without a terrible cost. Now labeled as one of Britains most wanted terrorists, and separated from the boy she cares for, Leyla and her father must risk undocumented travel through unchartered waters if they wish to find refuge. Across Britain, the fall out of Mr. McQueen's escape has escalated tensions between Anthropid and non-anthropoid communities, bringing them to an all time high. As Leyla and her friends grow closer to discovering the truth behind Anthropoids, she uncovers her own mysterious connection to the past and the truth behind her father's abduction.
