Pack Up The Moon by Kristan Higgins

After losing his vivacious wife to a terminal illness, a socially awkward engineer is guided through the first year of grief by twelve monthly letters she wrote before her death, each challenging him to take small, brave steps back into the world. Moving between memories of their love story and his painful, often funny attempts to rebuild, it traces his journey from isolation to connection, showing how love can light the path forward even after devastating loss.
