What struck me about Mary Shelley's The Last Man was that unlike other apocalyptic protagonists, these heroes seem to learn nothing through their jaunt with the plague, and they have had about 300% more time to figure it out than others.
At the close of Can you Forgive Her? readers are asked to follow suit and forgive Vavasor -- easily -- for what she has done. As a reader in the 21st century I could really care less about her jilting Grey; I once jilted a lover. What I struggle to forgive in Vavasor is her insistence that she can never want to forgive herself.
