For readers who fell in love with Sarah Cavendish in book one, The Road to Harmony, the fight for her heart isn't over. It's only just beginning. Sarah has already done what no Cavendish daughter is meant to do; chosen a man her world says she isn't allowed to want. Choosing him was the easy part. Now the forces standing against her have names, and standing, and patience. A clergyman with his own claim on her attention. Out of the shadows, a scorned woman with lies and a story to tell; a society, and a Parliament, that forgives everything except a woman who refuses to know her place. Even the ones who love Sarah most are not certain the cost of this marriage is one she should be asked to pay. Sarah has made her choice. Whether the world will let her keep it is another matter entirely. Set in the last years of the Regency era, as old certainties begin to give way to a new one, The Threshold of Harmony is Book Two of the Beyond Harmony trilogy, and the question haunting every page is the one no one, not even Sarah, can answer yet: will love be enough?
