Becky soars and then plummets. First up, up, up, to the heights of society. Then down, down, down, to being suspected of adultery with Lord Steyne and being left by her husband. Amelia loses her husband to death by Napoleonic bullet, her family wealth to bankruptcy by Napoleonic invasion, and her son to adoption.
Again the two women's stories sync up somewhat, even though the paths they took to get to their lowest points are as different as can be. Still, at the climax of the novel, both Becky and Amelia have lost everything of value. Becky's respectability, high social status, and a chance at great financial success are gone. Gone too are Amelia's two loves, her comfortable lifestyle, and her self-respect and dignity.
