"Flint Larson has known when he was going to die since he was eight because of the Half-Life Institute, and he is spending the last forty-one days quietly with his divorced parents; September is a vibrant aspiring scientist who wants to cure 'half-life', especially since she has met Flint--but their time together is getting short".

For five days teenager Hannah Ashton has been living a nightmare because Greater Houston is devoid of people and totally silent, but then she finds Leo Sterling, a boy from her school whom Hannah considers to be both hot and trouble; together they set out to explore their city, and their own emotions--but above all they need to find out what has happened to their world, or risk being separated forever.
