Lila Black faces her greatest challange yet as she takes herself, her dead lover and the AI in her head into death's realm. The Quantum Gravity series, set in a world where our reality mixes with other dimensions that are the homes to Faeries, elementals and demons, is unique in modern SF - a series that is willing to incorporate legend, myth and magic while maintaining a rigorous approach to scientific and pyschological reality. And in Lila Black, Justina Robson has created an enduringly strong yet quirkily human and flawed heroine.
