Another novel I'd label as 'unique' has to be 'The Time Traveler's Wife' by Audrey Niffenegger. It's quite an intense read and although I wouldn't say it was one of my all-time favourite books, it was definitely one of a kind and the story has managed to stay with me ever since.
Within the chick lit world, Cecelia Ahern is an author with an incredibly distinctive style of writing. Her books have an enchanting and magical element to them which I fell in love with after having read 'If You Could See Me Now.' When I think of the word 'unique', Cecelia's story-telling immediately comes to mind, so she definitely belongs on this list!
I personally didn't really enjoy 'Extremely Loud and Incredibly Close' while I know a lot of people consider this an absolutely amazing read. However, I have to agree with the fact that it is original and it wasn't like anything I'd read before.
Probably the most recent book on this list and one that was quite unique to me. 'The Dead Wife's Handbook' tells the story of Rachel, who died a year ago and is now able to occassionally look down at her family and friends, most importantly her husband Max and daughter Ellie. It's the first book I read completely told from the perspective of someone who's dead; someone who isn't in heaven or hell (if you believe in those places), but somewhere unknown, somewhere inbetween. A wonderful and original read.
I read Kim Izzo's 'My Life in Black and White' in 2013 and it was one of my favourite reads of that year. Once again, a very original novel and I personally haven't read anything quite like it before. The story takes place partly in real life and partly within the script of a film noir, which results in a thoroughly enjoyable and captivating reading experience.
I love Meg Cabot. She has written so many amazing novels; I can't get enough of her books. I think a lot of people wouldn't probably describe her work as 'unique', but 'Boy Meets Girl' was unique to me because it was the first book I read in which the story was completely told through e-mails, journal entries, instant messages, scribbled notes, to-do lists, etc. I can distinctly remember how much I loved this way of telling a story and up to this day I get excited about books that only consist of letters/e-mails/diary entries... I don't know why exactly, but I just really enjoy it!
