Here Burns My Candle by Liz Curtis Higgs

(@LizCurtisHiggs) A mother who cannot face her future. A daughter who cannot escape her past. A timeless saga of love and betrayal, loss and redemption, flickering against the vivid backdrop of eighteenth-century Edinburgh. Here Burns My Candle is a historical novel, based on the beloved Old Testament story of Naomi and Ruth, set in another time and place to demonstrate the timelessness of God's Word.
