Sarah Shannon is a scientist working at the cutting edge of black hole research. She is also a woman seeking to cope with the impending death of her wife, Rhona, the love of her life. Unable to come to terms with this inevitable loss, she has embarked on an affair with her work colleague, Akshai; and that’s only the start of things getting complicated.

Something has gone wrong with Sarah and Akshai’s ground-breaking simulations of black holes. When they are able to correct the errors the system abandons their simulations, instead spitting out equations as if demanding a response. When they answer, the system takes over their lab and starts to transform their equipment - forcing them to flee. They are left suspecting the impossible: First Contact.

As Sarah’s employer steps in and seeks to take control, she risks losing access to her own work. Worse still, when they fled the lab she and Akshai had to leave Rhona behind, and Sarah will do whatever it takes to get her back.
