1900's: The Wonderful Wizard of Oz by L. Frank Baum barely made the cut for the first decade of the 1900's as it was first published in 1900. I read this book last year and thoroughly enjoyed following Dorthy on her adventures in Oz.
1910's: For this I chose another childhood classic, The Secret Garden by Frances Hodgson Burnett, first published in 1911. This was one of my favourite books as a child and made me want a secret garden of my own!
1920's: Probably the easiest pick on this list; The Great Gatsby by F. Scott Fitzgerald, first published in 1925, is considered by many to be the embodiment of the 1920's.
1930's: Rebecca by Daphne du Maurier was first published in 1938 and it's one of my all time favourite books. I highly recommend it to anyone who loves Gothic literature.
1940's: Another book targeted towards younger readers; A Tree Grows in Brooklyn by Betty Smith, first published in 1943, is a fantastic coming of age story about a young girl in early 1900's Brooklyn.
1950's: Another easy pick, The Lord of the Rings by J.R.R. Tolkien, first published in 1954 is another childhood favourite.
1960's: My favourite book that I was forced to read in high school; To Kill a Mockingbird by Harper Lee, first published in 1960, is one of those quintessential American classics everyone should read at some point.
1970's: I was told once that I hadn't read "proper" vampire fiction until I had read The Interview with a Vampire by Anne Rice, first published in 1976.
1980's: This was the hardest decade for me to find a book for. I ended up picking Norwegian Wood by Haruki Murikami, first published in 1987.
1990's: There were several childhood favourites I could have gone with for this decade but I ended up picking The Golden Compass by Philip Pullman, first published in 1995.
