The light between us / Katie Khan.

Thea and Isaac first met at University, on a lovely evening when a magnificent natural phenomenon took place in all its glory. Theirs was an instant connection, but it never went further than friendship. Because then and now, eight years later, Thea only has eyes for her work. Not only her course, but also an extraordinary project. Thea is determined to battle against the dusty minds of her sceptical supervisors to prove that time travel is not just the stuff of science fiction. And she has never told anyone the reason why. But when one of their friends goes missing in an experiment, Isaac and Thea must work together to find her - forcing them to re-examine their own friendship. Is it really as platonic as they used to think?
