Nova #21

Although his actions will have serious consequences for when he returns home to Earth, Nova takes the day off from school to fly into the heart of the Chitauri Empire and search for his father whom he has learned had been living as a slave forced to battle in the alien race's gladiatorial games.

Sam makes it to the race's heavily-guarded homeworld of Chitauri Prime, but discovers his father has already led a prison break and is now lost somewhere in space aboard a ship with limited capabilities which the young Nova cannot track.

Although Nova #21 doesn't reunite Sam with his father, it does confirm for Sam that the former Nova is still alive and (like many other of the former gladiators) searching for a way home. It will be interesting to see how long the comic keeps his father lost in space and just what happens to Sam's space-fairing extra-curricular activities once he does return to Earth. Worth a look.
