The Grandmaster Plan for Aging Up

It's a contemporary setting. It's actually set between Australia and England, where I grew up near the beach in Northern England. In terms of research, I just actually do a lot. So now that you've had one novel, you've got one novel under your belt and this is your second one that you've just submitted. What's the grandmaster plan now? Because are you starting on the third novel? And are you continuing the trend of aging up? And will that be for older young adults or adults?
