Having grown up in an animal-loving, outdoors family, I've always felt a strong attachment to and respect for the natural world. Whilst writing my novel, I realised this was an opportunity to do something more and so I began looking for charities that I could donate a percentage of my sales to. There was no shortage of worthy causes, but in the end I decided to pledge a minimum of 4% from the sales of The Spark to the Worldwide Veterinary Service (WVS). They're a small UK charity, providing sustainable veterinary resources to animal organisations all around the world, working with all types of species. WVS is run by incredible, inspirational people, and my hope is that in some small way I can help them continue with the valuable work that they do. If you ever have a free moment to visit their site and take a closer look at the help they provide, I'm sure they would greatly appreciate it.
