Better than Sci-fi by stephenopolos reviews
Drop a star trek s.c.e. heavy cruiser starship into a stargate universe, add a group of people who think their energy abilities are magic and stir... Harry grows up watching star trek, while an accidentally-made-sentient star ship watches over him. Sorry I'd put Bones up as a character but i'm only allowed two categories in the listing and stargate eventually overpowers.
