Day after day, the two women talk to each other during the sittings, revealing truths, fragilities and strengths. But does Isla know of the writer's long involvement with Martìn? Or that her husband had chosen Valeria for the years ahead? Amidst their own private turmoil, the stories of their lives are exchanged - and as the portrait takes shape, we watch these complex and extraordinary women struggle while the love of their lives departs, in an unforgettable, breathless tale of deception and mystery that captivates until the very end."--Publisher description.
