Problem: Hawthorne's Scarlet Letter is a tale of secret love, adultery, and sadness. Every person should read this timeless American novel at some point in their life. The strength of Hester Prynne is unusual for novels composed during the time this was published, and is therefore a revolutionary literary work. My only complaint is the length of "The Custom House," however horrible this sounds, I would just skip it, it does not add to the plot of the novel anyway.
Solution: Positive
