The Rainbow Bridge — Aubrey M. Flegg

Book 2: The Louisetrilogy
Over a century has elapsed since Louise sat for her portrait. The painting has passed from person to person, unsigned and unvalued. Then, in 1792, as Revolution sweeps through France, Gaston Morteau, a lieutenant in the Hussars, rescues the canvas from a canal in Holland. Louise becomes a very real presence in Gaston's life, sharing his experiences -- the trauma of war, his meeting with Napoleon. When events force Gaston to give up the painting to the sinister Count du Bois, Louise becomes embroiled in a tale of political intrigue and Gothic horror.In the ashes of the Delft explosion, Louise made a choice for life. Now she has to face the realities of love, loss and pain that this life brings.
