Every moment of human existence is governed by uncertainty. Jane Howard became convinced of this at the age of thirteen, when she told her constantly quarreling parents that she would never marry or have children. The next day, her father left the family, forcing her daughter to go through life with a huge guilt complex. Uncertainty will interfere in Jane's life more than once: when she applies for graduate school at Harvard and unexpectedly falls in love with her supervisor, when she decides to help her father and pays for this, a career in the financial sector, when she meets a person with whom she wants to break her promise made in childhood - and as a result, she will lose everything. Despite the blows of fate, Jane again and again found the strength to rise. But where is the limit after which you should no longer try to take life into your own hands and it is better to accept the inevitable and leave this world?
