My shelves are a real mixture of fiction, non-fiction, reference books and poetry. I have a passion for social history so there are shelves of read & tbr relating to people and places through time - my main weaknesses in terms of history are WW2, London and New York. I also love poetry so have tons of poetry books - many I just pick up and buy but havent dipped into yet!
Fiction wise I'm happy with a darn good story in most genres as my shelves will show - I actually buy alot of books based on their covers so I have all sorts here but they LOOK intriguing.......
