Rabbit Series by John Updike, book of a lifetime

I read Rabbit out of order. It's four books – four and a half, if you include the late novella, Rabbit Remembered – each one written at the end of a decade, between 1960 and 1990: Rabbit, Run, Rabbit Redux, Rabbit Is Rich and Rabbit At Rest. But I didn't know that when, in WH Smith in Brent Cross circa 1988, I picked up Is Rich, read one sentence and thought "well obviously I'm buying this". When I found out that there were two prequels to that book, I was simultaeneously dismayed – like someone who realises he has somewhat spoiled Back To The Future's 1 and 2 by watching 3 first – and excited, because it meant there was so much more yet to read.
