One idea that I got a few days ago is an adventure with a lot of historical events.
A title idea I have is Wake Up! or Pay Attention!
The general idea is that a boy is so engrossed in technology and his own little world that he doesn’t see anything that’s happening in the world around him. One day he is forced out of his own little world when a person pops up on his computer screen with an urgent message for help. This person is a time traveller who is trying to go back and fix certain events in history and at the same time make it a learning experience for a brat of a kid who thinks he doesn’t need to know about any of these things.
