This audiobook is narrated by an AI Voice. In snow-covered Helsinki, rational-minded Elina begins hearing a haunting lullaby that feels less like imagination and more like memory. Then she meets Luca, a cellist whose unfinished melody matches the music already living inside her. As dreams of another century grow clearer and hidden letters are discovered inside an old cello, the two are drawn toward a love story that may have begun long before either of them was born. Torn between science and impossible recognition, Elina must decide whether their connection is coincidence, inherited memory, or a promise strong enough to survive across winters.
