The cover is not the best oof. Harry is a fragile child. Rainbow eye is a rare condition which gives the human colour changing eyes depending on mood. They need to feel love otherwise it snaps, and they turn emotionless. They can change their eyes at will though. It was Christmas (yes I changed it) when Voldemort attacked them. Harry's twin brother, Evan Potter, was wrongly declared as the Boy-Who-Lived. Harry is taken away by Dumbledore and snaps. The Nebulas. An oh so strange group. Not known to anyone besides themselves. They are infamous for catching Death Eaters but were given no name...
