HARMONY and STEVE draw closer and spiritual war wages when heaven meets hell. Christian contemporary singing sensation, daughter of Christian radio and media family counselor icons, HARMONY HARPER, has spent her entire life serving God. From teen sensation to celebrated adult Christian contemporary music artist, she regularly plays sold-out concerts everywhere she goes. Nearing thirty, and nearing burnout, Harmony heads to her mountain cabin hideaway to commune with Christ and compose some new music. Hard rocker STEVE SLAYER faces an ultimatum: keep rocking life the hard way and watch his organs fail due to addictions, or, sober up – for real this time – and live. Hiding out in the mountains of Oregon, he spends weeks detoxing. Finally strong enough to venture into town, he comes face to face with Harmony. Over the next several weeks, the two become unlikely friends as Steve learns to love and trust God, and mutual attraction surprises them both. Once news of their budding romance reaches the world, no one is happy. Not her people – not his people. Then letters written in blood start arriving. An attack on a concert threatens more than just their lives. Harmony and Steve realize the threats might just be real. Can Harmony and Steve discover who wants to destroy them, or will the enemy bring their house down in a dissonance that strikes at their very souls?
