What if your soulmate lived a century before you—and the only way to reach them was through music and rain?
In 2025 Seattle, physicist Alina Voss spends her nights chasing impossible theories on time travel. Her only companion is an old piano left by her grandmother—and a haunting melody titled "Nocturne for Rainy Days." When a storm rolls in and she plays the tune, something extraordinary happens: a voice from 1925 answers.
Elijah Hart, a charming jazz pianist in Harlem, hears her music—and her voice. Across a hundred years of rainstorms and longing, the two form a bond that defies logic and time itself. Every note played strengthens their connection, but every storm threatens to break it.
As Alina dives deeper into the mystery—discovering her grandmother may have known Elijah too—she must race against time to stabilize a fragile rift before it's gone forever. But with each passing storm, love grows, danger deepens, and the past and future begin to collapse into one.
