Mark Twain’s last decade roars with intrigue and yearning as Lynn Cullen brings our attention to his complicated relationship with Isabel Lyon, his personal secretary who has been long overlooked. A great read for fans of Z and The Paris Wife. Cullen illuminates the darker, outermost corners of Samuel Clemens’s later years, the caged lives of his daughters, his dying wife, and a woman ‘Mark Twain’ was never meant to love.
