You will most appreciate 'Freddy and Fredericka' if you are familiar with the story of the Fall, the Good Hermit, 'Tom Jones,' 'Huckleberry Finn,' 'Paradise Lost,' 'Henry V,' and 'My Cousin Vinny.' That doesn't mean that you can't enjoy or understand it on an emotional level, free of all allusion, which is the test of any book of fiction.
