DemonOut, or, Gift from a Bodysnatcher

When Makala Gilver makes the mistake of befriending bodysnatcher demons, her body is snatched and a demon becomes a clumsy version of Makala. That qualifies it as a human, which is what bodysnatcher demons want. It can now live above ground, move into Makala's house and live the life she was living.

    However, there is one thing in her life that the demon doesn't want and so it leaves the item on the sunspinners' door step. This leads to so many problems the only solution the family can think of is to permanently  remove the demons from Seattle. If only they knew a way to do that.
