"House Rules," by Libby Fischer Hellmann, in A Woman's Touch, Sniplets Publishing. 2010.
I've been reading the e-anthology, A Woman's Touch. So far this is my favorite. Marge and Larry Farley take a vacation in Las Vegas, but Larry isn't much impressed. First, he loses a bundle in a casino, then he finds the great outdoors "too hot. And dusty. Let's go back." His view changes when he finds a mysterious box in the sand. When he brings it back to the hotel all hell breaks loose. Turns out somebody ditched the box in the desert for a reason. Turns out a whole lot of people want it back. No one is who they seem and Marge, who is a self-help book kind of person, may or may not be able to rescue Larry from the mess he has gotten them into.
A fun read.
