Indeed, Percy Jackson among others. But it all began with Mary Pope Osborne's Tales from the Odyssey series which they read at school and then performed as a play. Great books, your kids would probably enjoy them.

My Gran definitely has her own set of worries all relative to her reality. For us when we're older, who can imagine? We'll probably have robots that care for us that will have learnt exactly how we like our food to be made, and how to help us clean ourselves etc... But what will the environment look like? Will our kids be safe and financially secure? Some of the worries we have today will always be there. Others will be shaped by the world we live in. -Tom
