Lucienne Kundera is an astrophysicist visiting Paris to accept an award being given to her for her discovery of a black hole. An award that is slated to be presented by her mother, Helene Kundera, a physicist with a secret past. While in Paris, memories of her past overwhelm Helene, and she makes an attempt at suicide. While in the hospital with her mother, Lucienne meets Dr. Assam, who may be able to help her uncover her mother's secret past.
The book intertwines the present day story of Lucienne with the history of Helene, which made for a few difficult transitions. Outside of that, the prose was beautifully crafted and the physics behind the story was well researched.
