Children of Khivian

Danny is a boy who doesn't care for school. He has no friends and the relationship with his mother is god-awful. He comes home one day to find a creature in his room. A Khivian, it calls itself. He's never heard of these things, hell, nobody has. He teams up with the creature to make sure his whole town isn't destroyed. He'll soon figure out that there is in fact strength in numbers, whether he likes it or not.
