Think about a story you've written. Where is it set?
Now think about where you live. In the city, the countryside, a small town, a suburban hub? A farm, a trailer, an apartment, a cottage, a motor home? In North America, or Asia, or Chile?
Some of us naturally write stories set where we live. In the vegetable patch in back of our farmhouse, or in the driveway of our one-storey suburban house, or the elevator to our twenty-fifth storey penthouse.
Other writers pick a location that's as exotic as possible. If they live in Canada, they'll set their story in Thailand or Bengal or Nigeria. (Or, if they're from Nigeria and live in Wales, like Atinuke, author of the lovely Anna Hibiscus series, they'll write a story set - in part - in Canada!)
While writing about a place you DO know well may sound dull, the truth is that some of the most-loved children's books take place in settings that are very similar to places the authors live or lived. Places they know well, almost like the back of their own hand.
And the good news is that wherever you live, it's bound to be exotic to somebody.
Right now, I'm visiting Toronto with my family, after nearly two years living in Israel. This is my home town; I grew up here.
