'I Capture the Castle' by Dodie Smith is a wonderful book about an eccentric family and how they must cope in the 1920's to 1930's. Cassandra is the heroine and she 'captures life at the castle', where lifes through her diary. The book, although lacking in a highly adventourous plot, keeps you entertained and interested. It's romance, basically, but not the kind you may think. I think this is a novel that shows one of the grittier side to the romantic genre.
All in all, I recommend this book, along with other great authors, lie J.K Rowling!
