The Beach Twins — David Feist

The Beach Twins are the vacationing Cloe and Kassidy Robinson who, along with their youngest sibling Cain, are spending the whole month of July this summer at their rich Uncle Eckenstine's mansion. And in Orlando, Florida no less.The girls are sixteen years old. So what does the wealthy Uncle Eckenstine do? Not much. He just buys Cloe a car. Not to be outdone, he then gives Kassidy a motorboat. Well, this should be the vacation of a lifetime. As long as they are careful, nothing can go wrong for the girls, right? No, guess again. The girls' only real job is to babysit their six year-old brother Cain for the thirty-one summer days. What could go wrong with that? Plenty!
