Ilya is a hero of our time. He is well educated, does what he loves, has a good income, understanding friends, but at the same time he is immensely lonely. He is trying to understand himself, his relationships with women, friends and his restless boss... The novel takes place in the American state of California. Ilya works at a biomedical startup in Silicon Valley. He perceives the world around him with sarcasm, talks about the meaning of life, tries to find his way by means that are not always accepted in society. The novel “Challenger” is about the high-tech generation; those who were born before their profession appeared. High technologies transform not only the world around us, but also their creators - the Challenger generation, whose childhood began with the take-off and death of a spaceship, and who are all too familiar with the internal emptiness, comparable only to the Challenger Deep - the lowest point on the Earth's surface, located in the Mariana Trench. Contains profanity.
