About this book:

Disgraced by heartbreak and seeking solitude, violinist Isabelle takes refuge in the ancient, isolated Hawthorne Manor. Rumored to shelter restless souls, the manor’s silence is quickly replaced by an unsettling sense of presence and fleeting echoes of music not her own. Driven by an irresistible curiosity, Isabelle unearths a trove of hidden journals and letters belonging to Edmund Beaumont, a poet who lived in the manor over a century ago. As she delves into his words, she discovers his artistic struggles, his yearning for an unseen muse, and his desperate attempts to compose a symphony called "The Echoed Promise," a melody that eerily mirrors the one haunting her own dreams.

The mystery deepens with the discovery of a hidden music box, a delicate wooden flute, and a silver locket containing a faded photograph of a woman and a lock of golden hair. Edmund's later letters reveal his increasing obsession with his music, his forced engagement to a woman he disdained, and his fear that he cannot keep the promise intertwined with his haunting symphony. Isabelle finds herself drawn into his world, experiencing vivid dreams and fleeting, spectral glimpses of Edmund, feeling an impossible connection across the centuries. Reading the poignant diary of Lillian, the woman from the locket, Isabelle uncovers the tragic truth: Lillian was Edmund's true, forbidden love, and her heartbreaking death occurred in the very reception hall where Edmund's engagement was announced, sealed by the music they shared and a promise tragically unkept.

Armed with the complete, hidden score of "The Echoed Promise"—dedicated by Edmund to "My Isabelle"—and understanding the profound sorrow that has tethered their spirits to the manor, Isabelle realizes her purpose. She must play the completed symphony on the manor's antique harmonium in the very hall where Lillian died, fulfilling the centuries-old promise and bringing peace to their lingering souls. The successful performance allows Edmund and Lillian to find their freedom, but reveals to Isabelle the manor's true secret: it is a nexus, a bridge beyond, capable of connecting souls across time. Now the guardian of this bridge, Isabelle opens Hawthorne Manor as a retreat for those seeking inspiration and healing, discovering that the Echoed Promise is not just one love story, but a timeless symphony of connection, a testament to the enduring power of love and art to transcend all boundaries, forever after the echo.
