What is my favorite author?
Is that a trick question?
I don’t have one.
Yes, I’m serious.

I don’t have one. I have several. Austen, Hemingway, Wolfe. Michael Cunningham. Regina McBride. Ann Patchett. Wilde has now been added to the list. Countless authors who I’ve only read one of their books but I loved with a passion, and they are on my Goodreads list to read more and I just haven’t gotten back to them yet. John Green up there is probably on that list too now.
Why can’t I narrow it down to just one? Geez. They all have different qualities that I love. Every book is different and each means something to me at a different point in my life. And every time I reread them, I love them in different ways.
It would be like picking a favorite topping on my pizza, or a favorite beer.
And yes, I know some people like ONLY pepperoni, and ONLY Bud Lite. That is so totally not my style. Sometimes I want mushrooms and a Belgian. And sometimes I want hot peppers and a red ale. Or maybe a porter, or a triple or….dammit now I want a beer.
It’s almost the long weekend folks!
As I Lay Reading 
I think the simile you are looking for is: itslike picking a favorite child. No mother can call a favorite… and neither can we with books.
