Is size everything?

Ah ha - that got you intrigued didn't it? No I'm not talking about Mr Big or Mr Thumb (one of my exes, a whole different story!) I am talking about books. Most of the books on the market are 5" x 8" but mine have been produced as 6" x 9" which means they don't really slip into your handbag unless you have one the size of a suitcase (I do but many don't). I am thinking of producing Strings Attached as a 5" x 8" to bring it in line with books on the market in my genre and to make it more...
