What happens to a young woman who, for the first time in her life, leaves a small town for a large resort center, leaving her husband and daughter at home? She enjoys the sea, the sun, she is open to new acquaintances; she is dizzy by young wine and courteous men... Among all this celebration of life, a man appears on Marina’s path who takes advantage of her inexperience and provincial naivety. She cannot resist male strength and arrogance. A pleasant trip to the sea turns into drama. But this is just the beginning... The novel “The Law of Conservation of Love” has many faces. A Moscow businessman and an amorous provincial woman, a cruel mercenary soldier and the “capital lioness”, a journalist and a tramp, a millionaire and a kept woman - they will all play their role in the fate of the main character. This book is about what real feelings mean in our lives.
