I come from a very large extended family. It is usually a good thing, although sometimes can be a little overwhelming especially if you want to keep a secret!
But It's the closeness I have with my family that has helped me write stories with characters full of life like the grandmother who always knows exactly what to say to make everything better. The older brother or sister who, while picking on us when we're younger, turns out to be our most trusted confidant.
My hope is that as you read my novels, you find yourself connected to the characters as you would your own family. Hoping for their happiness and rooting for them when they stumble and their dreams fall short.
