How important is a length of a book to you? What is your preferred length? Personally I like a book between about 300-350 pages. That is not always the case. I read Divergent in 2 days which is almost 500 pages. I loved Beautiful Creatures and that was LONG. I read Breaking Dawn which was 750 pages (though I didn't enjoy it very much). I really enjoyed Harry Potter and I liked the length because it was so full of action.
Some books are perfect in 200 pages. If I stay at 224 pages really packed a punch! I really like it when a book can have such an impact in a small number of pages. Quick reads are great when you have a free evening.
I don't mind too much about length. when it gets close to 500 it does put me off a bit but it won't stop me from reading it. Short books and long books both have a place in my reading schedule and I do try to work it so I'm alternating to keep things fresh!
