Charlotte believes she is an alien: an COMET ORPHAN, left behind on earth after a family holiday from their comet. Now 28 and working in a Lancaster print shop, only her boyfriend and a well meaning group of alien supporters believe her story as an alien. As the SEXY AF society (Search for Extraterrestrials, Aliens are Friends) prepares for the return of Charlotte's comet, she is torn apart by two homes. Is she going to stay on Earth with her boyfriend (who's gearing up for a proposal), or should she reunited with her long lost family on her home planet?
