A Tale of a Tub
A Tale of a Tub was the first major work written by Jonathan Swift, arguably his most difficult satire and perhaps his most masterly. The "Tale" is a prose parody divided into sections each delving into the morals and ethics of the English. Composed between 1694 and 1697, it was eventually published in 1704. It was long regarded as a satire on religion, and has famously been attacked for that, starting with William Wotton.
A Swiftly Tilting Planet
This is the third book of the Time Quintet, preceded by, in publication order, "A Wrinkle in Time" (1962) and "A Wind in the Door" (1973). However, this was not the chronological order. Though "Many Waters" was written and published later than "A Swiftly Tilting Planet", it takes place earlier with respect to the characters. The last book in the Quintet, "An Acceptable Time" takes place a generation after "A Swiftly Tilting Planet", and is part of the Polly O'Keefe series of books. The larger "Murry-O'Keefe" series (the Time Quintet plus the books of Poly/Polly O'Keefe) contains three novels between "A Swiftly Tilting Planet" and "An Acceptable Time" in terms of character chronology. These are "The Arm of the Starfish", "Dragons in the Waters", and "A House Like a Lotus."
