This is both an epistolary novel and a history of archival research leading to the disclosure of an almost detective family secret. The narrative intersects time and space, Russian, French, Italian, English and even Provencal languages, letters and a girl's album from the past and today's e-mails. A kaleidoscope of events and feelings allows a very young person who has fallen into someone else's environment to find care, love and a new, numerous family. The novel "In memory of the sweet Steph" tells about very different - in character, age and even languages - people who wander around the corners of someone else's, but as a result of their life. A story that goes far into the past, which seemed inexplicable and even scary, suddenly turns into the joy of finding each other by people.
