The Martian Dream is to have your own home, work a nice steady job and raise 1.2 well behaved offspring. Fiona and Ashley feel well on their way to accomplishing this when they make a down payment on their new home.
The dream state descends from there. Just add water and alien shenanigans will commence leading to an adventure of Extra-Solar dimensions. Don't forget to pay the Homeowner's Association fee as learn about the options in Utopian Estates, a Next You novel.
