I'm looking for a story in which two boys flee their planet with the father of one of them who is fatally killed in the escape and becomes the artificial intelligence of the spacecraft. although yang boys + -12 years of age they are married. I think the first adventure of them is in a lunar station or something ...
And There is another story about a being in a spaceship that can travel in time and rescues several boys(4) from Earth rithe before they die. one of these guys is bad. and ultimately escape. and causes problems.
