Teenaged Leyla McQueen, who lives beneath the ruins of a submerged London in 2099, joins a prestigious submersible race in the hope of clearing her father's name before encountering government corruption and a hidden world.

London Shah is a British-born Muslim of Pashtun ethnicity. She has lived in Britain's capital for most of her life, via England's beautiful North. When she's not busy re-imagining the past, plotting an alternate present or dreaming up a surreal future, she's most likely drinking copious amounts of tea, eating allthe sweets and cakes, strolling through Richmond Park or along the Thames, getting lost on an evening in the city's older, darker alleyways-preferably just after it's rained-listening to punk rock, or losing herself in a fab SFF book or film.
