Joseph Luzzi, author of the new book In a Dark Wood, offers five recommended reads, one of which is A Tale of Two Cities: ". . . We are in Dickens Land, where story and imagination reign supreme, and where we are led onward by the most large-hearted of guides."
And here's a list from 2014 that I missed at the time: Kathryn Schulz's list of "The 5 Best Punctuation Marks in Literature." Number 4 is the colon in the first sentence of A Christmas Carol: ". . . This sentence is insane, or anyway destined to foment insanity in the grammatically prissy. It has death, a dangling participle, and a wonderfully garrulous narrator with some kind of unmentionable Victorian-era disease: wandering colon. It is great."
