The cat

"Single mother Elise is completely devoted to her eleven-year-old son; he is her whole world. But that world is destroyed in one terrifying moment when her son is killed in a car accident just outside their home. Suddenly alone, surrounded by memories, Elise faces a future that feels unspeakably bleak--and pointless. Lost, angry, and desolate, Elise rejects everyone who tries to reach out to her. But as despair threatens to engulf her, she realizes, to her horror, that she cannot join her son: She must take care of his beloved cat. At first she attempts to carry out this task entirely by herself, shut away from a frightening new reality that seems surreal and incomprehensible. But isolation proves to be impossible, and before long others insinuate themselves into her life--friends, enemies, colleagues, neighbors, a former lover--bringing with them the fragile beginnings of survival."--Publisher's website.
