I need to know a good title for a sci-fi story. it has to involve two teenage girls, aliens and a ugly looking boy who ends up to be one of the girl’s cousin. They attend a junior high school, and they are left home alone for most of the story. One of the girl’s street is split in half because of a few cracks (due to the aliens). Also the aliens are allergic to the color orange, and they can put flames out to any houses which are made out of brick.
