Which books are told in the most interesting / creative/ mind bending ways? How does it add to the book overall?
My all time favourite is Ella Minnow Pea where the book is a series of letters. The characters have to think of more inventive ways to write their letters as an increasing number of letters are outlawed as the book progresses.
Honourable mentions include:
Maribou Stork Nightmares where the narrator is trying to suppress his dark past by allowing himself to slip into hallucinations of a whacky south African safari adventure.
Flowers for Algernon where the narrator becomes more articulate by taking part in a scientific experiment.
The Book Thief
Death is the narrator but also acts as a character, which means you have a limited-omniscient first person narrative.
Death is eternal and has vast knoledge, but “his” knowledge and understanding of humans is restricted to “his” interacting with them during times of loss and destruction. As a result, Death is fascinated by us but suspects that we may not be worth his sympathy since all we do is kill one another, making “his” existence one of unending, demanding work.
