This week I've been seeing more and more people get their pre-orders of my book. And it's now confirmed - it's here! You can order it through Amazons or Waterstones in the UK and you'll get it straight away. It's also available in Ireland, the US and elsewhere!

The book comes with a website to compliment it, which I'm still working on!
