The wonderful people at Glasses Direct have a great book blog called GD Book Worm, which you can find here.
At the moment, they are running a competition to win a Kindle Fire. Just leave a review of a book on the blog, with a photo of yourself reading the book to enter.
There are already some great reviews on the site, and they are currently doing a feature about favourite books for summer reading.
Go on - have a go, you have to be in it to win it!
Good luck x
